FZW32-12 Outdoor Vacuum Load Break Switch 12kv
FZW32-12/T630-20 type outdoor high voltage isolated vacuum load switch (hereinafter referred to as the load switch) is a three-phase AC 50Hz, rated voltage 12kV outdoor high voltage switch equipment, suitable for breaking, closing urban or rural distribution system load current and fuse break transfer current. Equipped with motor mechanism and controller can be used as line breaker or automatic breaker. Due to the use of new insulation structure design and vacuum arc extinguishing chamber, the load switch has obvious fracture after breaking, and has the function of isolation switch, in addition to the breaking capacity is large, no oil, so no pollution to the environment, no explosion risk, long electrical life and
maintenance free.
