Application:
ZW32-24high voltage vacuum circuitis a outdoor switch equipment of power system which ratingtri-phase AC 50Hz, 24kV.
It is used to make and break load current, overload current and short-circuit current.Act as the protecting and controlling unit for substation and industrial mining enterprises’ equipments. Applicable to locations that need frequent operating in rated current or under repeatedly on/off shortcircuit current.
As the power grid's breaking switch, it can realize the distribution network automation after installation of the controller.
