Transformers can be divided into: distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, furnace transformers, rectifier transformers, reactors, anti-interference transformers, lightning protection transformers Transformer, box-type transformer test transformer, corner transformer, high current transformer, excitation transformer, etc.

Transformers are the basic equipment for power transmission and distribution, and are widely used in industry, agriculture, transportation, urban communities and other fields. There are about 17 million transformers operating on the grid in my country, with a total capacity of about 11 billion kVA. Transformer losses account for about 40% of power losses in transmission and distribution, and have great energy-saving potential. In order to accelerate the promotion and application of energy-saving transformers, improve the utilization efficiency of energy resources, and promote green, low-carbon and high-quality development.
