This kind of switch applies to the 1 &3phase, combination oil-immersed transformer,rated voltage of 10/35KV,current30-250A

This kind of switch applies to the single-phase, three-phase, combination oil-immersed transformer of electrical power with frequency of 50HZ, 60HZ, rated voltage of 10KV, 35KV, rated current of 30A~250A; the voltage-regulating places are central part, neutral point, can be directly fixed on the box-cover of the transformer, under the non-excitation condition regulating and changing.
