Product Description
GW8-72.5 neutral point isolating switch
Description:
GW8-72.5 type neutral point isolation relationship single-phase AC 50Hz high voltage switchgear, rated current: 630A, 1250A. In the case of voltage and no load, it is used as the neutral point grounding circuit of the dividing and closing transformer. It is also used at the time of railway automatic blocking signal operation device. And it can be used in single pole. Among them, the anti-pollution isolating switch can meet the requirements of users in heavily polluted areas, and can effectively solve the pollution flashover problem that occurs in the operation of the isolating switch.
