Recently, China Electric Equipment Group’s subsidiary, China XD Xi’an Electric Equipment Co., Ltd. (XD XIAN), successfully developed China’s first and largest three-phase integrated 220 kV power transformer (model SFP-1150000/220) for million-kilowatt-class units, passing all required tests in a single trial. This milestone not only showcases China’s independent innovation capabilities and global leadership in high-end power equipment but also injects "Chinese expertise" into the global energy transition through open collaboration. It marks a new era in China’s power equipment manufacturing sector, characterized by breakthroughs in core technologies, smart production capabilities, and internationalization.

Innovation Breakthrough: Core Technology Localization Leads Industry Transformation
As a national leader in China’s power equipment sector, China Electric Equipment has consistently prioritized innovation as its core driver. For this project, the R&D team achieved breakthroughs using a world-first electromagnetic calculation methodology, overcoming technical bottlenecks such as component overheating under high magnetic leakage conditions. Innovations like multi-dimensional cooling optimization and a composite shielding system reduced product losses by 15% compared to international standards and improved temperature control precision by 20%, with key performance indicators reaching global leading levels. The group has established a full-chain innovation system spanning "basic materials-core components-complete equipment," backed by 12 national-level R&D platforms and over 10,000 authorized patents. With R&D investment intensity exceeding 6% for three consecutive years, the company continues to lead industry-wide technological advancement.

Smart Manufacturing: Full Industrial Chain Strengths Empower Global Energy Infrastructure
Leveraging world-class smart manufacturing capabilities, China Electric Equipment has built a digitalized closed-loop system from design simulation to precision production. The transformer utilized fully automated winding robots and a digital twin assembly system, achieving micron-level precision in critical processes and maintaining a 99.8% first-pass yield rate for five consecutive years. With 15 smart factories and 32 IEEE/IEC-certified production lines worldwide, the group boasts an annual transformer production capacity of 50 million kVA, serving over 130 countries and regions. The successful delivery of the Jiangxi Shenhua Jiujiang Power Plant project not only supports China’s "dual-carbon" goals—enhancing regional grid efficiency by 15% and reducing annual CO2 emissions by 480,000 tons—but also provides a replicable "China solution" for overseas projects through standardized, modular designs.

Open Collaboration: Chinese Standards Engage Deeply in Global Energy Governance
As a core member of 15 international standards organizations, including the International Electrotechnical Commission (IEC), China Electric Equipment is actively integrating Chinese technical standards into global energy systems. The three-phase integrated transformer technology has been included in the Belt and Road Energy Cooperation Promotion Catalog, while its electromagnetic calculation models were adopted by the International Council on Large Electric Systems (CIGRE) as recommended algorithms. The group has supplied over 100 ultra-high-voltage equipment units to Southeast Asia, the Middle East, and Latin America, driving a 35% increase in exports of domestically produced core components. Additionally, it established joint R&D centers in Europe and formed technology-sharing partnerships with more than 40 global energy enterprises, transitioning from "product exports" to "ecosystem collaboration."

The transformer’s deployment will address Jiangxi Jiujiang’s power supply gap during the 14th Five-Year Plan period, boosting regional grid reliability by 30%. Its technological achievements have already been applied to international projects such as Saudi Arabia’s Red Sea NEOM and Chile’s carbon-neutral mining zones. Moving forward, China Electric Equipment will deepen its "innovation-smart manufacturing-openness" integrated development model, delivering higher-quality equipment for new power systems and fostering global energy interconnectivity through greater openness, ultimately contributing Chinese strength to building a shared future for humanity.
