ZW32 outdoor vacuum circuit breaker
Release time:2015-06-06 01:48 Read:Time


 
● Overview
ZW32-12 outdoor vacuum circuit breaker (hereinafter referred to as circuit breaker) as the rated voltage of 12 kv and three-phase ac 50 hz outdoor distribution equipment Is mainly used for open circuit close load current overload current and short circuit current in power system for substation and industrial and mining enterprises for protection and control in power distribution system, and the site of rural power grid frequent operation

Running of the circuit breaker has small volume, light weight, coagulate frost prevention from coagulate frost free maintenance etc., can adapt to the harsh climate conditions and pollution environment
