Foil coil is mainly used for small and medium-sized transformers with capacity less than 2000KVA. The advantages of foil coil are: good mechanical strength, not easy to deformation, can withstand s...
In the working process of transformer, a lot of heat will be produced, which seriously affects the performance of transformer. During the operation of transformer, the loss of winding and core wil...

The transformer insulator, metal body and so on are often with some sharp angle and burr, so the electric charges under the action of electric field intensity will conc...
As know oil-type transformers are the most common form of transformers. When an oil-immersed transformer is in use, the heat generated by the coil and iron core is first transferred to the insulati...
