Product introduction:

40.5kV High Voltage Vacuum Circuit Breaker is a kind of outdoor HV switching devices used in three-phase AC 50Hz. 40.5kV. It uses spring operating mechanism or electromagnetic operating mechanism; it can be controlled to switch-on/off remotely; it can also be used to control energy storage and switch -on/off manually. The breaker conforms to standards of GB 1984-89AC HV breaker and IEC56AC HV breaker. It is used for protecting and controlling distribution systems in transformer substations, operating in gear and protecting the circuit in country electric nets, industrial and mining enterprises when short-circuit occurs. The breaker has porcelain post structure. The upper knob insulator has vacancy arc-extinguishing chamber while the nether one is post knob insulator.
