Summary
ZW32-12 outdoor pole mounted switch is an outdoor power distribution equipment with rated voltage of 12kV and three-phase AC 50Hz. It is mainly used to break and close the load current, overload current and short circuit current in the power system. It is applicable to the protection and control of power distribution systems in substations and industrial and mining enterprises and the frequent operation of rural power grids.
