Detailed Product Description
Product overview
Outdoor HV AC Self Extinguishing SF6 Circuit Breaker is used in the electrical system of 3 phase AC 50Hz,132kV /145kV as its control and protective equipment, and also a connecting circuit breaker for switching loading current, cutting off fault current and switching over power circuit through various wiring ways in the power plant and substation.
Product standard
This circuit breaker is compliant with GB 1984-2003 HV Circuit Breaker and IEC 56 HV AC Circuit Breaker. It is insulated and arc-extinguished by SF6, complying with self extinguishing principle. Working with the spring actuator, it has the following features: powerful breaking capability, long electric life of 20 times, lower active power and high reliability.
