Product Description

1. Transmission 40.5kV Manual Vacuum Circuit Breaker Draw Out Type

"Vacuum circuit breaker" is named after its arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are both high vacuum; it has the advantages of small size, light weight, suitable for frequent operation, and no need for maintenance of arc extinguishing. The application in the network is more popular. Vacuum circuit breaker is an indoor power distribution device in a 3~10kV, 50Hz three-phase AC system,
