The power equipment manufacturing industry continues to deepen technological innovation, focusing on the high-end, intelligent, and lightweight development of transformers. It has consistently overcome core technological bottlenecks, achieving full domestic production of several new transformer models, breaking down technological barriers in high-end equipment, and driving a leapfrog improvement in the industry's technological level. For a long time, there have been technological shortcomings in the core components and key processes of high-end special transformers and high-power power electronic transformers, with some high-end equipment relying on imports, hindering the high-quality development of the domestic power equipment industry. To address this, industry research institutions and manufacturers have collaborated, focusing on core areas such as material development, structural optimization, and intelligent control, continuously promoting technological innovation.

Recently, a high-voltage, large-capacity dry-type transformer has achieved complete independent control of its core technologies. This equipment abandons the traditional oil-immersed structure, adopting new insulation materials and a modular design, possessing advantages such as fire resistance, environmental friendliness, convenient operation and maintenance, and strong adaptability. It can be widely used in scenarios with stringent safety and environmental protection requirements, such as urban core business districts, underground substations, and densely populated residential areas. The overall structure of this equipment has undergone thousands of operational simulation tests, and its core performance indicators, such as withstand voltage, load capacity, and anti-interference, have reached advanced levels in the industry. It has completely achieved the localization of core materials, core components, and manufacturing processes, filling several technological gaps in the field of high-end dry-type transformer self-sufficiency.

In addition to high-voltage dry-type transformers, new product technologies such as silicon carbide power electronic transformers and high-frequency intelligent transformers continue to be implemented. These new transformers integrate power electronics technology, intelligent sensing technology, and automatic control technology. Compared with traditional equipment, they have advantages such as lower energy consumption, faster response speed, smaller size, and higher level of intelligence, enabling precise adaptation to the needs of new scenarios such as new energy grid connection, power supply for computing centers, and smart grid dispatching. Through technological iteration, the industry is gradually breaking free from the predicament of low-end homogeneous competition, significantly improving the supply capacity of high-end products, and significantly increasing product added value. In the future, the industry will continue to focus on the adaptation needs of new power systems, increase investment in cutting-edge technology research and development, and promote the continuous upgrading of transformer equipment towards high efficiency, energy saving, intelligent controllability, and integration.
