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...
The coil of transformer is an important part of transformer. It is said that the heart of coil type transformer is very important to transformer. In the transformer, the coil is the part of the cir...
The thermal stability of the insulation material is the main factor affecting the life and overload capacity of the oil-immersed transformer. By explaining the preparation process, physical and che...
Distribution transformers normally have ratings less than 200 kVA,[2] although some national standards can allow for units up to 5000 kVA to be described as distribution transformers. Since distrib...
