Transformers are important basic equipment for power transmission and distribution, widely used in industries, agriculture, transportation, cities, and other fields. Their development is closely related to the development of the power industry, national construction investment, and industrial enterprise investment. In recent years, the country has made a large amount of infrastructure investment, which has driven the rapid development of the power industry and further promoted the scale growth of the transformer industry.

The development trend of the transformer industry shows that the development of ultra-high voltage and extra high voltage industries is conducive to optimizing China's power grid and power supply layout, promoting the coordinated development of the power industry as a whole and regional economy, and effectively achieving the allocation of energy and resources. Therefore, the construction of ultra-high voltage and extra high voltage power grids has become an inevitable trend in China's power development, and in order to adapt to the development of transmission technology in China, transformers will also develop towards high voltage and large capacity.
