In recent years, the global energy structure has been undergoing profound transformation, with clean and low-carbon energy becoming the core direction of the power industry’s upgrade. Wind power, photovoltaic power generation, distributed energy storage and other emerging new energy projects are being rolled out on a large scale across various regions. Driven by the continuous investment and construction of these new energy projects, the market demand for special power transmission and distribution transformers matching new energy stations has maintained a steady upward trend, creating a solid market foundation for the development of supporting power equipment industries.   Different from conventional thermal power generation, new energy power generation is highly dependent on natural environmental conditions. Wind speed, solar irradiation, seasonal climate changes and other factors lead to obvious output volatility and intermittency in wind and photovoltaic power generation. In addition, most new energy power stations are built in remote and complex outdoor areas, including mountainous regions, coastal tidal zones and arid desert areas. Such harsh operating environments put forward stricter and more comprehensive technical standards for supporting power equipment. Transformers for new energy scenarios need to possess excellent weather resistance to cope with extreme high and low temperatures, strong overload capacity to adapt to fluctuating power output, and outstanding anti-corrosion performance to resist coastal salt fog, desert sand erosion and mountain humid oxidation, far exceeding the performance requirements of traditional grid equipment.   Facing the differentiated demands of new energy application scenarios, domestic power equipment manufacturing enterprises have actively carried out product upgrading and iterative optimization. Combined with the actual operating conditions of new energy stations, enterprises have adjusted and upgraded the overall product design, focusing on strengthening anti-corrosion, moisture-proof, cold and heat resistance treatments for equipment shells and internal structural components. These targeted improvements enable the special transformers to operate stably for a long time in complex and changeable outdoor environments, effectively reducing equipment failure rates and later maintenance costs.   In terms of market operation, centralized packaged procurement has become the mainstream purchasing mode for large-scale new energy projects. This standardized procurement method not only simplifies the project construction process, but also brings continuous and stable bulk orders for professional power equipment manufacturers, effectively supporting the steady growth of corporate operating income. Meanwhile, the domestic new energy consumption system is constantly being improved, and the coupled development of energy storage equipment and new energy power stations has become a universal industrial application mode. This industrial change further expands the application scenarios and market demand space for power transformation equipment, extending the industrial demand chain continuously.   Compared with traditional power grid projects dominated by policy planning, the new energy industry features a higher level of marketization and more intense market competition. Product technology updates and iteration speeds are much faster, putting forward higher requirements on enterprises’ independent research and development capabilities and market response speed. Enterprises that take the lead in laying out new energy supporting equipment research and development, mastering core manufacturing technologies and accumulating rich scenario application experience can quickly occupy a favorable market position. By optimizing their business structure and focusing on the long-term growth track of the new energy industry, these leading enterprises are able to maintain continuous and stable order growth and gain sustainable competitive advantages in the industry.      

Transformer manufacturing is a core segment of traditional electrical equipment heavy industry, which has long depended on manual work for most production links in the past. The whole production flow covers winding, lamination, assembly, inspection and other multiple procedures, most of which were completed by skilled workers manually. The traditional production mode features complicated and fragmented processes, relying heavily on workers’ operational experience. This not only led to slow production speed and low overall operational efficiency, but also made it hard to standardize every production step. In recent years, with the continuous upgrading of industrial manufacturing technology and the popularization of digital industrial reform, the entire transformer manufacturing industry has ushered in a comprehensive wave of digital and intelligent upgrading.   A large number of mainstream manufacturing enterprises in the industry have phased out backward manual production methods, and gradually introduced high-precision automatic winding machines, fully intelligent sheet stacking equipment, as well as online real-time intelligent inspection systems. Through the introduction of new equipment and new technologies, enterprises have thoroughly optimized and restructured the original backward production process, realizing the overall upgrading and modernization transformation of old-fashioned production workshops.   After the popularization and application of the new digital management mode, the scattered production links of the factory have been effectively integrated. Production scheduling, raw material allocation, semi-finished product processing and finished product quality inspection are uniformly managed and centrally controlled through digital systems. This mode fundamentally avoids frequent operational errors and unstable quality problems caused by manual subjective judgment and operational negligence in traditional production.     It ensures that the quality, performance and specifications of transformer products in different production batches can remain stable and consistent. Meanwhile, intelligent automated equipment takes over a large number of repetitive, high-intensity and mechanized manual operations in the production process. This change greatly relieves the operational pressure brought by the long-term labor shortage in the manufacturing industry. Even in the peak sales season with a sharp surge of customer orders, enterprises can still arrange production in an orderly manner and accurately control product delivery cycles, effectively avoiding order delays and customer loss.     In addition, many leading transformer manufacturing enterprises have independently built and improved dedicated digital production management platforms. The platforms can track and display the real-time operating status of each production line equipment, daily energy consumption data of the workshop, and the progress of each order production in real time. Based on accurate data feedback, enterprises can carry out scientific and refined production management, timely adjust production arrangements, and optimize energy allocation. As a typical traditional heavy industry, the intelligent transformation of the transformer industry started later than that of emerging manufacturing industries.   However, thanks to continuous technological investment and iterative upgrading of production lines, the transformation has achieved extremely prominent practical results. The continuous optimization and upgrading of production lines have not only greatly lifted the upper limit of the overall production capacity of enterprises, but also effectively reduced labor costs, material waste and energy consumption, cutting down the comprehensive production cost in an all-round way. Ultimately, the industrial intelligent upgrading has significantly improved enterprises’ ability to cope with market fluctuations and operational risks, and comprehensively strengthened their core competitiveness in the fierce market competition.    

With the continuous acceleration of urban infrastructure construction and industrial upgrading, urban district substations, underground comprehensive pipe galleries, large-scale commercial complexes, as well as densely populated industrial parks have become key nodes of urban power supply systems. These scenarios feature dense personnel distribution, closed operating spaces and complex operational environments, which put forward higher and stricter standards for the fire safety performance, environmental protection indicators and stable operation capability of supporting power equipment.   Against this background, the market demand for high-performance flame-retardant and environmentally friendly insulation transformers has achieved a substantial and sustained increase in recent years. Traditional transformers mostly adopt mineral insulating oil as the core insulating medium, yet this conventional material has obvious performance shortcomings. Its flammability is relatively high, and it is prone to combustion risks once equipment fails or encounters external fire hazards. When applied in closed spaces and densely populated urban functional areas, it brings prominent potential safety hazards, greatly restricting the application scope of traditional oil-immersed transformers and failing to adapt to the current urban safe power supply layout.     Different from traditional mineral insulating oil, natural ester plant insulating oil boasts outstanding comprehensive advantages such as ultra-high ignition point, complete biodegradability and excellent flame retardant performance. The material can effectively avoid fire spread risks in case of accidental equipment failure, and will not cause environmental pollution due to leakage, which perfectly fits the usage requirements of closed and indoor power scenarios. Therefore, natural ester plant insulating oil has gradually replaced traditional mineral insulating oil in a large range, becoming the preferred mainstream insulating medium for transformers used in indoor power stations, urban closed pipe galleries and intensive commercial supporting projects.   On the basis of upgrading insulating materials, mainstream transformer manufacturers in the industry have further optimized and upgraded the overall equipment structure. By improving the box body sealing process, optimizing internal structural layout and strengthening the overall flame-retardant protection system, the operational safety factor of transformers has been comprehensively improved. The upgraded products can fully meet the stringent safety inspection and project acceptance standards of municipal public infrastructure projects, high-rise commercial buildings and urban supporting power engineering.   At present, power equipment safety compliance has become the primary core factor that engineering purchasers, property operators and urban power management departments take into account when selecting transformer products. The rigid market access standards and strict safety assessment requirements have forced the entire transformer manufacturing industry to speed up product iteration, technological upgrading and structural transformation.   After years of continuous research and development, testing and practical application, the production and processing technology of green insulating materials represented by natural ester oil has become increasingly mature and stable. The large-scale industrial production and widespread market application have effectively reduced raw material procurement and equipment production costs, laying a solid foundation for the large-scale popularization and application of fireproof and environmentally friendly power transformation equipment.   The dual upgrading of product safety performance and green environmental protection performance not only effectively solves the safety pain points of power equipment operation in urban intensive scenarios and standardizes urban power safety management, but also closely conforms to the national green low-carbon development and carbon neutrality strategic layout. This steady industry iteration has continuously released market potential for high-end green transformers, bringing sustained and stable growth momentum to the niche high-quality segments of the transformer manufacturing industry.      

Since 2026, the global transformer industry has witnessed explosive growth. China, leveraging its full industrial chain advantages, technological breakthroughs, and efficient delivery capabilities, has become the core supplier in the global market. Its products are exported to regions such as Europe, North America, and Southeast Asia. The export orders have been queued up until 2028, and the industry's prosperity continues to rise. Global Times. Currently, the global energy transition and AI computing power construction form dual core driving forces. Domestic "15th Five-Year Plan" power grid investment has fully kicked off, and cross-regional transmission projects of ultra-high voltage are advancing steadily. The construction of new infrastructure such as energy storage stations and park micro-grids is accelerating. This directly drives the batch signing and production of high-voltage and super-large transformers. At the same time, global AI data center construction has exploded, with the power per cabinet soaring from traditional 5 kilowatts to 100 kilowatts, leading to an exponential increase in the demand for high-power, low-loss, and stable dry-type transformers.   By 2025, the proportion of domestic high-end transformer orders related to computing power has exceeded 35%. In the overseas market, the European energy transition, the US $75 billion power grid expansion plan, and the demand for upgrading old power grids have been released simultaneously. The global average price of transformers has risen by over 60% year-on-year, and the delivery cycle has extended from 30-60 weeks to 115-130 weeks. Some large products even require a waiting period of 4 years. Chinese transformer enterprises have seized the global market with significant advantages. In terms of technology, domestic leading enterprises have been deeply engaged in the ultra-high voltage field for many years, mastering core technologies such as insulation design and withstand voltage treatment, and successfully developing the world's first 500 kilovolt vegetable oil transformer, filling the international gap in high-voltage-level environmentally friendly transformers. The product can reduce carbon emissions by 72.8 tons and improve the adaptability to extreme weather by 15°C.   In terms of delivery efficiency, China has 60% of the global production capacity, and regular orders can be delivered within 10-12 months, while emergency orders can be compressed to within 8 months, only one-fifth of the cycle of European and American manufacturers. In 2025, China's transformer export total value reached 64.6 billion yuan, increasing by 36% year-on-year. In the first two months of 2026, the export growth rate further increased to 61%, and the export to the European market increased by 88.1% year-on-year.   Greening and intelligence have become the core directions of industry upgrading. From the policy side, China is accelerating the elimination of high-energy-consuming outdated equipment, and the proportion of first-level energy efficiency and ultra-low loss transformers in procurement has continued to increase, forcing enterprises to optimize their production capacity structure. From the technical side, natural ester insulating oil and new composite materials are widely used, and the proportion of environmentally friendly insulating transformers has steadily increased; the penetration rate of intelligent transformers exceeds 35%, with functions such as real-time parameter monitoring, fault warning, and remote control, suitable for the construction of smart grids. At the same time, solid-state transformers are gradually emerging from the laboratory and accelerating their commercialization process, and will become the core direction of industry technological innovation in the future. Industry insiders analyze that in the short term, the global supply-demand imbalance pattern is difficult to alleviate, and China's transformer export advantages will continue to be consolidated; in the long term, as the industry's chain matures and technology iterates, it will undergo a deep transformation towards green and low-carbon, intelligent and efficient. However, it is necessary to note that global trade barriers, fluctuations in raw material prices, and the shortage of high-end talents still need to be addressed. In the future, domestic enterprises need to continuously increase R&D investment, strengthen intelligent manufacturing capabilities, and consolidate global market share while promoting China's transformation from a transformer manufacturing giant to a technology powerhouse.

In recent years, driven by global energy structure adjustment, aging power grid renovation and new energy construction expansion, the market demand for power infrastructure renovation and upgrading has seen a concentrated surge across the world. Most overseas countries and regions face prominent bottlenecks in local power equipment manufacturing. Restricted by insufficient domestic manufacturing capacity, backward production layouts and slow production line expansion progress, local manufacturers struggle to keep up with the rapidly growing market demand. This has directly led to a significant extension of the overall supply cycle of power transformation and distribution equipment. In particular, a large number of European and American countries rely on traditional local manufacturing systems, whose power equipment delivery cycles often stretch across several years. The long delivery waiting period seriously restricts the implementation rhythm of local aging power grid renovation projects, and also hinders the construction progress of supporting industrial and commercial power projects, resulting in a prominent mismatch between local power supply capacity and market demand.   After decades of continuous technological accumulation, industrial iteration and production layout optimization, China’s transformer manufacturing industry has built a complete and independent whole-industry-chain production system. The industry boasts large-scale production capacity, rich and complete product specifications, covering high-end engineering special transformers and conventional civil distribution transformers of various voltage levels. It is fully capable of undertaking large-scale national engineering complete equipment supporting projects, as well as bulk orders for small and medium-sized civilian power distribution products. In addition to outstanding production and order undertaking capabilities, domestic enterprises have formed standardized and standardized production management processes. Strict factory quality inspection systems, stable product quality control and mature cross-border logistics export channels have further consolidated the comprehensive competitive advantages of China’s transformer equipment in the global market, making domestic products increasingly recognized by overseas clients.   Faced with the dilemma of long delivery cycles and high procurement costs of local power equipment, overseas engineering contractors and power project developers have gradually shifted their procurement focus to Chinese-made power equipment. Purchasing high-quality Chinese transformers helps them effectively shorten project construction cycles, control overall project procurement costs, and improve the economic benefits of engineering projects. Supported by full-chain independent raw material supply, standardized large-scale assembly line production, stable quality control and efficient export service systems, the export scale and market share of domestic transformers have maintained a steady upward trend. Under the background of the global structural imbalance between power equipment supply and market demand, China’s transformer manufacturing industry has been continuously filling the supply gap in the international market. By virtue of reliable product quality and cost-effective advantages, Chinese manufacturing has grown into an indispensable core supply force for global energy infrastructure construction and renovation.   At present, many core manufacturing regions in China have formed well-developed and highly concentrated transformer industrial clusters after years of industrial cultivation. These regional clusters feature a full set of supporting facilities and a sound localized supply chain system, covering raw material supply, component processing, finished product assembly and factory testing. Relying on the unique strengths of complete local supporting resources, flexible product customization capabilities and fast response delivery efficiency, a large number of specialized small and medium-sized manufacturing enterprises have achieved differentiated development. These enterprises focus on segmented market tracks and mainly target decentralized small and medium-sized overseas orders that are easily overlooked by large manufacturers. Inside the industrial clusters, the division of labor among different factories is highly refined and efficient. Every production link including iron core processing, precision coil winding, sealed box assembly and rigorous finished product testing is closely connected with zero redundant procedures, which greatly streamlines the overall production process and effectively shortens the product delivery cycle.   Different from large manufacturers that focus on high-end large-scale power grid equipment, these small and medium-sized enterprises avoid the fierce homogenized competition in the high-end equipment market. They precisely target the huge market demand for civilian power distribution renovation and small industrial and commercial power supply projects in emerging markets such as Southeast Asia, the Middle East and South America. In response to diversified overseas market requirements, these manufacturers can flexibly adjust product design parameters, modify product structures according to different national grid voltage standards, regional climatic conditions and on-site installation environments. Meanwhile, they can fully adapt to the local market’s mainstream procurement budget range and long-term power usage habits, delivering highly matching customized products for overseas customers.   In the international trade market, standardized bulk large orders are mainly occupied by leading large-scale enterprises, while diversified small-batch and multi-category customized orders have become the core source of stable operating revenue for regional small and medium-sized transformer manufacturers. These enterprises have accumulated good market reputation and stable customer resources through long-term standardized foreign trade services. With flexible service modes, quick order response and thoughtful after-sales support, the regional industrial clusters are steadily expanding their overseas brand influence and market coverage. The differentiated positioning and complementary operation of large, medium and small domestic transformer enterprises have further optimized the overall overseas layout of China’s transformer industry. By giving full play to the collaborative advantages of industrial clusters, domestic manufacturers keep exploring and tapping the potential of overseas sinking markets, further consolidating China’s dominant position in the global transformer supply chain.      

Driven by the fast iteration and innovative breakthroughs in modern power electronics technology, advanced wide-bandgap semiconductor materials represented by silicon carbide have achieved mature mass production and large-scale industrial application in recent years. Benefiting from the continuous improvement of core device performance and processing technology, solid-state transformers, as a new generation of intelligent power conversion equipment, have completely stepped out of the laboratory research and experimental verification stage, and are speeding up the pace of industrial commercialization and market promotion. Unlike traditional electromagnetic transformers that rely purely on electromagnetic induction principles for voltage conversion and power transmission, this new type of power equipment adopts advanced power electronic conversion technology.   It features a compact and lightweight structural design, effectively reducing overall equipment volume and floor space. Meanwhile, it greatly lowers operational energy consumption and power loss during long-term grid operation. Most importantly, it supports flexible and fast switching between AC and DC power modes, which traditional equipment cannot achieve. This unique functional advantage makes it highly adaptable to various emerging power application scenarios, including grid-side energy storage power stations, regional microgrid systems, smart distribution grids and new energy power generation projects, perfectly matching the development needs of modern intelligent power systems.   To accelerate the industrial landing of solid-state transformer technology, many leading domestic electrical equipment enterprises have carried out in-depth industry-university-research cooperation with professional university electrical engineering research institutions in recent years. Focusing on the practical application pain points of small and medium-sized solid-state transformer equipment in actual operating environments, the two parties have jointly completed repeated prototype testing, operational verification and product performance optimization. The research team has effectively improved the equipment’s internal program logic and intelligent control procedures, optimized the internal heat dissipation structure and thermal management system that restrict long-term stable operation, and solved common problems such as equipment heating and signal delay in high-load operation.   Through continuous process adjustment and structural upgrading, the manufacturing and assembly costs of solid-state equipment have been effectively controlled and gradually reduced. At this stage, the optimized and upgraded solid-state transformer products have been put into trial operation in multiple scenarios such as grid-connected energy storage stations, industrial park microgrids and new energy demonstration projects. Actual operating data shows that the equipment runs stably with low failure rate, verifying its good practical application value and market promotion potential.   Despite the outstanding performance advantages and broad development prospects of solid-state transformers, the industry still faces certain development bottlenecks at this stage. Restricted by the high manufacturing cost of core silicon carbide power devices and the imperfect supporting industrial technical standards and specification systems, solid-state transformers cannot fully replace traditional electromagnetic transformers in the short term, and large-scale market penetration still takes time. Even so, the technological upgrading trend of the transformer industry towards intelligence, high efficiency and low energy consumption is completely irreversible.   With the continuous maturity of the upstream and downstream industrial chain, the gradual localization of core components and the continuous expansion of industrial mass production scale, the overall manufacturing cost of solid-state transformers will show a steady downward trend. In the long run, backed by the national new power system construction and the large-scale development of new energy industries, the market penetration rate of solid-state transformers will keep rising steadily. This innovative power equipment will surely become the core development direction and key breakthrough point of technological innovation and industrial upgrading in the domestic transformer manufacturing industry.      

China’s cross-regional ultra-high voltage (UHV) power transmission infrastructure construction has been advancing steadily and systematically in recent years. A large number of key national power transmission and transformation projects have entered centralized tendering, formal construction and phased implementation stages, creating strong market demand for high-end power equipment. This ongoing wave of major engineering construction has directly driven the batch signing, production delivery and official commissioning of high-voltage and ultra-large capacity power transformers.   Different from conventional civilian distribution transformers, such high-end UHV equipment features extremely high technical barriers, rigorous design standards and intricate production and manufacturing procedures. The whole process covers precision component processing, integrated structural assembly and strict performance testing, requiring long-term technical accumulation and professional manufacturing experience. Due to the high entry threshold in terms of technology, equipment and qualification, the UHV transformer market has long been occupied and dominated by industry leading enterprises, forming a relatively stable market competition pattern with no drastic homogenized competition.   Industry leading manufacturers have focused on the research, development and production of ultra-high voltage power equipment for many years, maintaining deep cultivation in this segmented high-end track. Through long-term engineering practice and continuous technical iteration, these enterprises have accumulated mature and reliable core technologies in key links such as special insulation structural design, high-strength withstand voltage processing, and equipment adaptation to extreme working conditions.   Their self-developed and optimized equipment products can fully meet the strict requirements of long-distance large-capacity power transmission, as well as stable and safe operation under complex terrain and harsh climate environments. At present, with the accelerated construction of the new power system, the cross-provincial and cross-regional optimal allocation of power resources has become an important development trend. The surging demand for long-distance consumption and grid integration of large-scale new energy power has further boosted the continuous approval and implementation of various ultra-high voltage transmission projects across the country.   While major UHV projects are being pushed forward, the upgrading and reconstruction of urban and rural main power grids are also in full swing across the country. The continuous renovation of aging power grid facilities and the expansion of regional power supply capacity have driven steady growth in market demand for medium and high voltage power transformation equipment. The large-scale UHV engineering orders are characterized by huge transaction volume and long implementation cycles, which can bring continuous and stable operating revenue and profit support for leading power equipment enterprises.   Looking ahead, under the overall development strategy of cross-regional energy coordination and optimal resource allocation, the construction of ultra-high voltage power projects will maintain a steady progress with no slowdown trend. As the most critical core supporting equipment for UHV transmission lines, high-end power transformers have highly certain long-term market demand. The sustained construction of major projects will further drive the high-end transformation, technological upgrading and intelligent iteration of the entire transformer manufacturing industry.      

In recent years, the implementation of various local policies for energy conservation and carbon reduction has been steadily and comprehensively carried out across the country, covering all links of power production, transmission and distribution. Focusing on the key energy-consuming fields in the power industry, local governments have continued to promote special rectification and green renovation work. In the core industrial sector and urban and rural power grid operation and maintenance links, the elimination and replacement of outdated, aging and high-energy-consuming equipment have been accelerated simultaneously as scheduled. Among them, the green upgrading and iterative renovation of power transformers, as key basic equipment of power grids, has continued to advance in an orderly manner.   A large number of early-produced transformers that have been put into operation for a long time generally have low energy efficiency standards and prominent technical backwardness. Such equipment has high no-load and load operating losses during daily operation, and long-term continuous service will not only greatly increase the overall operation energy consumption and safety operation pressure of urban and rural power grids, but also significantly raise the long-term electricity cost and operation burden for industrial and commercial enterprises and public institutions. With the continuous advancement of energy-saving and low-carbon renovation work in various industries, the market demand for the replacement and performance upgrading of old transformers has continued to emerge and maintain a steady growth state.     In the centralized public bidding and procurement projects of national and local power grids, the access proportion of first-level energy efficiency and ultra-low loss transformers has continued to increase year by year. Meanwhile, the industry procurement access standards and technical indicators have been continuously tightened and optimized, forming a strict market access threshold. This effective policy mechanism fundamentally limits the circulation and application of backward, high-loss and inefficient transformer products in the power grid market from the source. Facing the dual changes of policy constraints and market rules, domestic transformer manufacturers have actively adjusted their production layout and product structure, gradually reduced and withdrawn investment in low-end backward production capacity, and concentrated core technology, production and market resources on the mass production and iterative optimization of energy-saving new products, so as to accurately adapt to national policy guidance and continuous changes in terminal market demand.   At the technical level, the wide popularization and application of natural ester insulating oil and new high-performance composite insulating materials in the industry has further optimized the comprehensive performance of energy-saving transformers. These new materials effectively enhance the environmental friendliness, safety and long-term operational stability of transformer equipment, enabling the products to adapt to complex and diverse application scenarios including urban core distribution substations, rural power grid stations and outdoor industrial power stations. Driven by the combined effect of top-down policy guidance and bottom-up autonomous cost reduction demands of the market, the replacement and renovation of traditional old power equipment has gained sufficient development space.     At present, the entire power transmission and transformation industry is in a critical period of comprehensive transition towards low-carbonization, energy conservation and high efficiency. In the long run, high-efficiency and energy-saving transformer equipment will continue to maintain a stable and sustained market growth trend.      

The digital infrastructure construction process has been advancing at a fast pace in recent years, and various intelligent computing centers and big data industrial parks across different regions are accelerating their establishment and formal commissioning. As more enterprises and institutions migrate business data and computing tasks to cloud platforms, high-density computing scenarios have become increasingly prevalent across the industry. This widespread industry transformation is driving the continuous heating of the market for specialized special transformers tailored for computing infrastructure.   Unlike conventional industrial and civilian power consumption scenarios, data center operation relies entirely on stable, sustained and high-quality power support throughout the whole year. Traditional ordinary distribution equipment, which is designed for conventional power supply scenarios, is unable to meet the strict 24-hour uninterrupted high-load power supply requirements of modern data center operations. As a result, the industry's demand for customized transformers with high overload capacity, low energy loss, and strong heat dissipation performance has rapidly increased in recent years.     To keep pace with the rapidly evolving market demand, many established power equipment enterprises have actively adjusted their research and development directions and product iteration strategies. These enterprises are deeply delving into the professional field of data center power supply equipment, focusing on targeted technical optimization and structural upgrading. They have specifically improved the internal structure of transformers, strengthened overall insulation performance and optimized systematic heat dissipation design, making equipment more adaptable to the closed, heat-prone and high-load complex operating environment of enclosed data centers. In addition to large core computing power hubs that generate massive procurement demands, newly built edge computing sites and supporting distributed energy storage projects are also steadily advancing, continuously releasing stable market orders for small and medium-sized special transformers with diversified specifications.   Correspondingly, the industry's overall development logic is gradually changing and upgrading. The extensive competition centered on simple basic production capacity and homogeneous products has obviously weakened and can no longer support the long-term development of enterprises. In the current market environment, scenario-based customization capabilities and technological differentiation advantages have become the core competition points for power transformer manufacturers. Domestic manufacturers, relying on years of accumulated practical experience and mature manufacturing technologies in power equipment production, have quickly entered the emerging data center power supply field.     These enterprises keep optimizing product performance and continuously enrich the matrix of specialized products to cover diverse computing scenario needs. Given the clear long-term expansion trend of the domestic computing power industry, the continuous construction of digital infrastructure will steadily drive the iterative upgrade of supporting power transformation equipment and effectively open up sustainable new market spaces for the whole industry.      

Entering the second quarter of 2026, the global energy infrastructure construction continues to advance steadily, and the construction pace of power transmission and transformation projects both at home and abroad has continued to accelerate. Driven by booming market demands at home and overseas, major transformer production plants across the country have maintained robust operating conditions with sustained high production enthusiasm.   According to the latest foreign trade statistics and market tracking data, the overseas market inquiry volume for mainstream transformer products has shown a continuous upward trend. Among them, distribution transformers, oil-immersed power transformers, and box-type transformer equipment, which are widely used in power grid construction and industrial power supply, have witnessed notable growth in overseas demands. Specifically, the order increments emerging from emerging markets including Southeast Asia, Central Asia, Africa, and Latin America are particularly significant, becoming the core growth engine of China’s transformer foreign trade business.     Faced with the surging overseas order volume, a large number of enterprises focusing on transformer foreign trade business are operating at full capacity. Most manufacturers have adjusted their production schedules accordingly and postponed their batch production plans to the second half of the year to cope with sufficient order reserves. Production workshops have long adhered to a stable two-shift operation mode to maximize production efficiency and ensure timely product delivery. In terms of comprehensive market competitiveness, domestic transformer manufacturers boast outstanding industrial chain advantages compared with local manufacturing factories in overseas regions.   The domestic industry has formed a complete and mature supporting system, covering core raw materials such as silicon steel sheets and copper materials, as well as auxiliary insulation materials and various structural components. All supporting materials can be procured locally and nearby, which greatly shortens the overall production and delivery cycle. Meanwhile, the complete industrial matching system also helps enterprises optimize cost management, presenting remarkable overall cost control advantages.   In addition, many developing countries are currently pushing forward the upgrading and renovation of outdated old power grids and the large-scale expansion of industrial park supporting facilities. The rapid development of global new energy industry also generates massive grid connection demands for photovoltaic and wind power stations. These multiple market demands jointly stimulate the market demand for conventional type transformers, consolidating the foundation of overseas market growth.     Industry insiders generally hold the view that such rigid overseas market demand will not decline rapidly in the short term. Relying on reliable production capacity and mature technological craftsmanship, domestic manufacturing enterprises will steadily consolidate their overseas market share. Moving forward, high-efficiency and energy-saving transformer products will gradually replace traditional products and become the mainstream choice for China’s foreign trade exports.      

     Last month, a group of clients from Russia made the trip to Xuzhou for one specific reason: to see the Huayu Transformer factory with their own eyes and watch exactly how their electric power transformers would be built. These weren't casual visitors. They came with a concrete project in hand. Several rounds of emails had already gone back and forth—technical specs, pricing, delivery schedules—all nearly settled. What remained was the final, non-negotiable step: an in-person factory audit. As they put it, "Trust is good, but seeing is better." The head of Huayu Transformer's International Trade Department accompanied the group throughout the visit. First stop: the production floor. To be honest, the shop tour ran quite a bit longer than usual. The Russian clients looked closely and asked even closer questions. At the winding station for oil-immersed power transformers, they leaned in to inspect the coil arrangement, then asked about insulation paper brands and temperature ratings. Over in the 110kV assembly area, they probed deeply into the details of core drying procedures and vacuum oil filling. Later it became clear why—winters in their part of the world are brutal, and the demands on a transformer's cold-start performance and insulation reliability are unforgiving.         The MES dashboard on the shop floor also caught their attention. Real-time production progress, quality inspection data, equipment status—all visible at a glance without needing anyone to explain. One client pulled out his phone and snapped a photo, remarking that this kind of transparent management is a big plus back home.            After the tour, both sides sat down for a meeting. The International Trade Department walked through Huayu Transformer's product portfolio again, with extra focus on the S20 series energy-saving oil-immersed transformers and the SCB18 series dry-type transformers—both models the clients had expressed interest in during earlier email exchanges. The technical team also took time to address the cold-climate concerns directly, explaining Huayu's established practices in low-temperature design, sealing structures, and insulation coordination.                The order is scheduled for production next quarter. And the team on the shop floor already knows where these transformers are headed. When you're building equipment bound for Russia, you know it's got to hold up through a Siberian winter.           

In the interconnected modern power system, various power equipment functions collaboratively, forming a complete system for power transmission, conversion, and regulation, providing a solid guarantee for power consumption scenarios across various industries. Among them, the Oil Immersed Transformer, as the core equipment for power grid operation, can be considered the power system's "heart," undertaking the core functions of power conversion and voltage regulation, and is an indispensable key carrier in the power transmission chain. The long-term stable operation of equipment is never the achievement of a single component, but rather the result of the precise coordination of the entire system. The Oil Immersed Transformer's long-term safe and efficient operation relies not only on the precise design of its core structure such as the iron core and windings, but also on the collaborative empowerment of various surrounding supporting components. These components undertake different functions such as protection, monitoring, and regulation, acting as the equipment's protective armor and intelligent central hub, comprehensively ensuring the transformer's stable operation, effectively avoiding operational failures, and extending the equipment's service life.   The power system equipment system boasts strong compatibility and completeness. Besides the core Oil-Immersed Transformer, the Dry-Type Transformer, with its excellent safety performance, is adaptable to various indoor and special power consumption scenarios. Box-Type Substations are highly integrated and flexible in layout, adapting to diverse power grid deployment needs and facilitating modular and lightweight power grid construction. Meanwhile, High and Low Voltage Switchgear plays a crucial role in circuit switching and power protection, serving as key equipment for controlling power grid operation safety and regulating power transmission order. These various power devices have clearly defined functions and complement each other, forming a complete power operation guarantee system from power conversion and substation integration to high and low voltage distribution management. A deep understanding of the core structure and supporting logic of power equipment, and a thorough grasp of the operating principles of various devices, are crucial for solidifying the stability of power system operation and improving the quality of power grid operation and maintenance, laying a solid foundation for the safe and reliable operation of the power network.

In high-load, high-critical industrial sectors such as mining, railway transportation, heavy manufacturing, and automated production, the stability and security of power distribution are crucial for ensuring continuous production line operation and mitigating operational risks. Traditional power equipment struggles to adapt to complex and harsh operating environments, easily experiencing performance degradation, safety hazards, and other issues, driving a new round of iterative upgrades for industrial power equipment.   For a long time, oil-immersed transformers have been commonly used in industrial power systems. However, these devices pose safety hazards such as oil leaks and spontaneous combustion, limiting their adaptability to high-risk industrial scenarios and failing to meet modern industrial safety and maintenance standards. In contrast, dry-type transformers, with their superior overall performance, are gradually replacing traditional equipment and becoming the mainstream choice for high-end industrial scenarios. This equipment eliminates the oil-based medium, eradicating the risk of oil leaks and fires at the source. It also boasts advantages such as resistance to harsh environments, ease of maintenance, and environmental friendliness. It can adapt to different voltages, loads, and operating conditions, exhibiting extremely high long-term operational stability.   The safe and efficient operation of industrial power systems relies on the coordinated support of a complete set of supporting equipment. Among these, the High and Low Voltage Switchgear plays a crucial role in circuit control, protection, and regulation. When used in conjunction with the Dry Type Transformer, it can construct a safe, controllable, and efficient power transmission system. Meanwhile, the Box Type Substation, as an integrated power support facility, can integrate the functions of various power equipment, adapting to decentralized and mobile operating scenarios such as industrial plants, railway lines, and mining sites, significantly improving the flexibility and practicality of industrial power layout.   As the global industrial electrification and intelligent transformation continues to deepen, various industries are increasingly demanding higher standards for the safety, customization, and stability of power support equipment. Customized Dry Type Transformers, adapted to harsh operating conditions, combined with complete sets of power equipment, will continue to empower high-end industrial sectors, laying a solid power foundation for safe industrial production and efficient operation and maintenance.

In the power grid operation system, transformer power loss is a core factor affecting the grid's energy consumption level, and transformer energy efficiency is a key lever for improving grid quality and efficiency, reducing costs and energy consumption. For a long time, the industry has focused on the operating performance of transformers under full-load conditions, neglecting the differentiated loss characteristics throughout the equipment's life cycle. Industry engineering research indicates that transformer iron loss and transformer copper loss, as the two core loss types of transformers, have drastically different operating patterns, respectively dominating energy consumption under no-load and load conditions. Accurately controlling the characteristics of these two types is crucial for achieving distribution transformer loss optimization and grid transformer energy waste reduction.   No-load Condition: Transformer no-load loss constitutes a continuous fundamental loss.   Under no-load operation with the transformer connected to the grid and the secondary winding open, the coil current is almost negligible, and the loss caused by coil resistance is essentially negligible. This makes transformer no-load loss essentially equivalent to transformer iron loss. Iron loss, a continuous loss generated during the magnetization process of the iron core, is determined by inherent parameters such as the core material and manufacturing process, and is unrelated to the equipment load state.   As long as the transformer is connected to the grid and operating at a stable voltage, iron loss will exist continuously around the clock, representing a fixed and fundamental loss during equipment operation. This continuous loss characteristic makes no-load iron loss a hidden energy consumption burden on the power grid. A large number of power distribution devices that are in a standby, no-load state for extended periods will accumulate significant energy consumption over time, forming an indispensable component of transformer lifecycle energy consumption.   Load Conditions: Transformer Load Loss Becomes the Core of Dynamic Loss   When a load is connected to the transformer and the coils generate operating current, transformer copper loss becomes the main variable in equipment energy consumption. Unlike the fixed iron loss, copper loss is generated by the winding resistance and fluctuates dynamically with changes in load current. Changes in load conditions directly alter the overall loss structure of the transformer.   During peak grid load periods, the equipment load rate is high, and copper loss increases significantly, becoming the dominant component of transformer energy consumption. Therefore, controlling copper loss is crucial for energy conservation and consumption reduction at this time. During periods of low electricity demand, light equipment load, or standby, copper losses decrease rapidly, while iron losses regain their dominant position. This dynamic pattern is a crucial basis for optimizing industrial transformer load performance and implementing energy-saving scheduling.   Loss Coupling Law: Determining the Optimal Operating Condition of a Transformer   The overall operating loss of a transformer is the superposition of iron and copper losses. These two types of losses, one static and one dynamic, are coupled to form a unique energy efficiency curve for the equipment, corresponding to the optimal load range with the lowest overall energy consumption. Engineering practice shows that when the transformer load rate is within a reasonable range, the ratio of iron and copper losses is balanced, and the overall energy efficiency of the equipment reaches its best state.   If the load rate is too low, the proportion of fixed iron losses is too high, and the energy efficiency of the equipment under light load decreases significantly. If the load rate is too high, copper losses will surge rapidly, leading to a continuous decline in the economic efficiency of equipment operation. Therefore, simply pursuing low losses under full load conditions is insufficient to adapt to the complex actual operating scenarios of the power grid; a loss optimization scheme must be matched with the long-term operating conditions of the equipment.   Engineering Applications: On-Demand Selection and Optimization for Long-Term Energy Saving   The fundamental difference between iron loss and copper loss provides a core basis for the formulation of transformer procurement loss standards and differentiated equipment selection and design. For power distribution scenarios with numerous long-term light loads and frequent standby times, the industry widely adopts new iron-core equipment. By optimizing the iron core material and process, no-load iron loss is significantly reduced, adapting to the energy-saving requirements of power distribution scenarios.   For high-load, continuous operation scenarios such as industrial plants, equipment R&D and manufacturing focus on optimizing winding structure and reducing winding resistance, effectively suppressing the surge in copper loss under high load conditions, and ensuring the long-term efficient operation of industrial transformers.   Industry experts state that the core of power transformer energy saving lies in adaptability optimization; there is no universal high-efficiency transformer suitable for all operating conditions. Only by combining the actual operating load characteristics of the equipment and balancing the optimized ratio of iron loss and copper loss can the transformer maintain stable energy efficiency throughout its entire life cycle, reducing long-term energy waste in the power grid from the source and contributing to the energy-saving and efficiency-enhancing upgrade of the power system.

The global energy system is undergoing profound reshaping, and the pace of electrification continues to accelerate. As a core hub of the power transmission and distribution network, power transformers support the stable operation of the entire power generation, transmission, and distribution chain, highlighting the industry's strategic value. Driven by multiple market demands, the transformer-related industries are entering a phase of sustained upward development, with significant adjustments in the industry's supply and demand structure and technological routes. Large-scale grid connection of renewable energy, the upgrading of aging power grid facilities across the country, and the continuous advancement of urban construction, coupled with the implementation of new power consumption scenarios such as computing data centers and electric vehicle supporting facilities, are jointly creating multi-level demand for power equipment. Different application scenarios place differentiated requirements on the performance, installation conditions, and safety standards of transformer equipment. Oil-Immersed Transformers, with their large capacity and high stability characteristics, are widely adaptable to large-scale wind and solar power bases and main transmission networks, becoming core equipment in the voltage boosting stage of energy bases.   In enclosed indoor environments such as urban areas, commercial parks, and computing data centers, operational safety and environmental adaptability are paramount. Dry-type transformers, with their advantages of no oil leakage and outstanding fire resistance, are gradually becoming the mainstream choice for power distribution projects in these areas. The demand for integrated power distribution solutions is also rising. Box-type substations integrate transformer and distribution functions, making them suitable for space-constrained construction scenarios such as scattered plots and new energy charging stations, significantly shortening on-site construction cycles. The reliable operation of the entire power transmission and distribution system relies on supporting switchgear. High-and-low voltage switchgear handles circuit switching and fault protection functions, forming a complete power supply unit in conjunction with various transformers and prefabricated substations, and is an indispensable component of power grid modernization.   Currently, the industry as a whole is characterized by strong demand, accelerated technological iteration, and constrained production capacity. Upstream and downstream players in the industry chain are continuously expanding production to alleviate equipment delivery pressures, but with global electricity consumption steadily increasing and countries continuously increasing investment in power infrastructure, the overall market demand remains at historically high levels.   The industry's development focus is shifting towards energy conservation, intelligence, and environmental protection. Manufacturers are continuously optimizing the internal structure of various substation and switchgear equipment to reduce operating losses, and incorporating digital monitoring modules to adapt to the dispatching and control needs of new power systems. In the long term, the rigid demand brought about by energy transition will continue to provide stable growth momentum for the transformer and related electrical equipment industry.

Dry-type transformers rely on air for heat dissipation instead of insulating oil, which puts them ahead of conventional oil-filled transformers in safety and eco-friendliness. Thanks to their space-saving build and flame-retardant insulation structure, these units can be set up inside indoor power stations, tunnel spaces, underground premises and industrial zones with dense personnel activity.   Mining sites present tough working conditions for transformers: thick dust, constant mechanical vibration, damp air and frequent swings in power load. We tailor dry-type transformers with strengthened insulation layers, anti-rust surface coatings and mature heat control setups, so the equipment runs steadily amid such severe surroundings.   Rail transit networks rely heavily on steady voltage to keep traction drives, signal gear, station power gear and tunnel distribution systems functioning normally. Dry-type transformers stand out with strong overload resistance, minimal partial discharge and quiet running features, perfectly fitting subway stations, railway power substations and urban transit power grids.   Heavy manufacturing factories run transformers under sustained high load demands. Bespoke transformer setups can fine-tune voltage stability, cut down power waste and lift the overall power supply quality for all production lines within the plant.

    A small team from Jiangsu Huayu Transformer Co., Ltd. landed in the capital of Uzbekistan, carrying a few product models and a thick stack of brochures in English and Russian. They had come for the annual Tashkent International Energy and Power Exhibition. Before the trip, the International Trade team didn't really know what to expect. Central Asia was still relatively new territory for Huayu Transformer. Sure, there had been a few inquiries here and there, and some clients had visited the factory in Xuzhou. But setting up a booth and showing the Huayu name at a local exhibition—this was a first. The team put the booth together clean and simple. In the center sat a cutaway model of an S20 series oil-immersed power transformer. Beside it, a sample coil from an SCB18 dry-type transformer. On the back wall, posters showing Huayu's track record with 110kV-class products and a few overseas project case studies. The booth wasn‘t huge, but everything that needed to be there was there.        One local engineer stopped in front of the S20 model and stayed there for quite a while. He asked a string of questions: What’s the short-circuit impedance on this transformer? What insulation class can you guarantee? How does the temperature rise control hold up under high ambient heat? The Huayu technical rep answered each one in detail. When they finished, the engineer nodded and said something that the translator rendered as: "Spec-wise, you're comparable to European brands. Price-wise, you're more competitive. We'll give this serious consideration back home."               The sample coil for the dry-type transformer drew its share of attention too. Several visitors ran their hands over the cast epoxy surface and took a long, close look. One operations engineer from a substation on the outskirts of Tashkent said that a lot of their aging transformers were due for replacement. The government had allocated special funds for equipment upgrades, and they were actively scouting electric power transformer suppliers—both domestic and international. "The finish on this coil," he said, "is cleaner than what I've seen from other booths around the hall."      

   Four of them flew in from Almaty, with a layover in Urumqi along the way. Nearly a full day of travel. They arrived in Xuzhou in the evening, and by early the next morning, they were standing at the gates of Huayu Transformer.      The lead client is a veteran electrical engineer with over twenty years of experience on the job. As soon as he walked in, he said something that the translator rendered as: "A lot of the equipment back home is still from the Soviet era. It's time for an upgrade. We came to China to find a transformer manufacturer we can work with for the long haul."      The tour started on the production floor. Unlike some of our previous visitors, these Kazakh clients paid exceptionally close attention to the tank structure and sealing design of the oil-immersed transformers. They lingered in front of the S20 series units for quite a while, asking detailed questions about weld inspection procedures and leak testing standards. It turned out that many substations back in their region are located near the Gobi Desert—blistering heat during the day, biting cold at night, and plenty of sand and dust. For an electric power transformer, the sealing integrity and thermal stability are anything but theoretical concerns.       One of Huayu's technical staff crouched down and walked them through the weld points one by one, explaining the non-destructive testing process and the acceptance criteria for pressure tests. The clients nodded along and pulled out their phones to snap a few close-ups of the weld seams. Then came the interesting moment, over in the dry-type transformer section. One of the clients stopped in front of an SCB18 dry-type transformer—and stayed there for a solid twenty minutes. He ran his hand over the surface of the cast coil, leaned in to examine the color and bubble-free finish of the epoxy resin, then walked around to study the nameplate on the back. Finally, he straightened up, exchanged a few words in Kazakh with a colleague, and said through the translator: "The workmanship on this transformer is better than what I saw at a factory in Turkey." That comment made its way around the shop floor. Nobody said much, but you could feel a quiet sense of pride settle in.   The business meeting in the conference room ended up being shorter than the shop floor discussion. The clients were straightforward: they had seen the products, they had seen the workmanship, they had seen how the place was run. Once back in Kazakhstan, they would compile a detailed technical requirements document and send it over. The initial interest: two 110kV oil-immersed power transformers and four 10kV dry-type transformers, destined for an industrial park renovation project on the outskirts of Almaty. Before departing, the group posed for a photo with the Huayu team at the factory entrance. As he climbed into the car, the lead client shook hands with the head of the technical department and said, "In winter, it drops to minus thirty degrees where we are. If your transformers can handle that, we'll be doing business together for a long time." The technical lead smiled and replied, "They can handle it. We've shipped plenty of units to Northeast China—same kind of winter."
