ZW8-12(G) series outdoor high voltage vacuum circuit breaker is rated voltage 12kV, three-phase AC 50Hz outdoor high voKage switchgear is mainly used to breaking Closing Rural power network, city network and small power system load current, overload current, short-circuit current. The product of the overall structure is box-type three-phase, three – phase vacuum interrupter placed in metal boxes，using SMC insulation material and interphase insulation and ground insulation, reliable performance，high dielectric strength.
ZW8-12(G)is ZW8-12 a composite by circuit breaker and isolating switch, called the combination of circuit breakers, use for disconnect switches.
This series of operating mechanism for the CT23-type spring operating mechanism energy storage can be divided into two kinds
