There are two main reasons for leakage: on the one hand, there are problems left in the transformer design and manufacturing process

Transformer faults can be divided into internal faults and external faults.

At present, the working lights and running lights of the machine tools use low-voltage transformers to provide 36V safety electric music.

Cold-rolled automotive sheets are developing towards ultra-deep drawing

Silicon steel, also known as silicon steel, is an iron-silicon alloy developed on the basis of industrial pure iron.

With the development of my country's electric power industry and the continuous deepening of the construction and transformation of urban and rural power grids, amorphous alloy core transformers, with their obvious advantages of low no-load loss, energy saving and environmental protection, are in line with the "saving resources and protecting the environment" advocated by the Chinese government.
