This switch device for 40.5 kv three-phase ac 50 hz system for acceptance and distribution of electric energy use, particularly suitable for frequent operation place (and can derive single busbar with bypass and dual bus structure). Circuit breaker can match domestic or ZN23 ZN12-40.5-40.5 vacuum circuit breaker, fixed installation, with CD10 series electromagnetic operating mechanism and CT19 series spring Cao Dong mechanism. Isolating switch with GN27 series products, prevent condensation impurity performance is good; Using agency disc type operating mechanism, five reliable performance. Mainly used in power plants, substations, and industrial and mining enterprises and substation.
