Vacuum Circuit Breaker Chassis Truck VCB Handcart of  High Voltage Withdrawable Switchgear by IEC Standard

Chassis truck is mainly used to holding circuit breaker, transformer and other components in the withdrawable switchgear, as auxiliary operation of components with busbar. When operation with internal mechanism of circuit breaker and other interlock mechanism of mid-placed cabinet, it can satisfy the interlock requirement of "5 preventions" stipulated in GB3906.
