Medium voltage AC SF6 Circuit Breaker

This series of outdoor high voltage live tank SF6 circuit breaker is a new type of outdoor high voltage electrical appliance with sulfur hexafluoride gas as arc extinguishing and insulating medium. The operating mechanism is divided into three types: (Type 1) manual energy storage spring operating mechanism, (Type II) motor energy storage spring operating mechanism, (type III) DC electromagnetic operating mechanism, and the circuit breaker body on various operating mechanisms is perfectly combined into a whole

General:

Compared with other 10kV outdoor circuit breakers, this product has the advantages of simple structure, excellent arc extinguishing and insulation performance, small operating power, high rated parameters, long electrical life and no maintenance period. Using this product can not only reduce the floor space. Reduce engineering cost and eliminate fire danger, and can greatly improve the reliability of power system.
