VTK-15/T5000-63F Indoor Vacuum Generator Circuit Breaker

VTK-15/T5000-63(F) HV indoor vacuum generator circuit breaker is installed between generator and transformer, for controlling and protecting generator. It simplifies the switchover program for station power and provides convenience for genset debugging and maintenance. It has been widely used in thermal power plant, hydropower plant, nuclear power plant, pumped-hydro energy and other new stations or the reform of ageing power stations. It could also be used for control and protection switches of equipments for large-scale substaions, high-load electro-industrial and mining enterprises. The breaker conforms to GB/T11022-1999, GB311.1-1997, JB3855-1996, JB/T8738-1999 and DL/T427-2000.
