ZW32 12kv circuit breaker ac vacuum switch 24kv High Voltage ac circuit
breaker Outdoor for Switchgear earthing switch
ZW32-12 series outdoor pole-mounted vacuum circuit breaker is a kind of outdoor
three-phase AC power distribution equipment at 12kV and 50Hz, mainly used for
closing the load current and opening overcurrent and short circuit current in the power
system. It can be used as a section switch in the distribution line, branch line and ring
main and as a incoming switch in rural grid, industrial and mining enterprises, residential
areas, construction sites, etc.
