ZW7-33 Outdoor High Voltage Vacuum Circuit Breaker

The 33kv circuit breaker is a kind of outdoor HV switching devices used in three-phase AC 50Hz 33kV. 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 GB1984-89 AC HV breakerand IEC56 AC 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. The breaker is suitable for the place where-frequent operation is allowed. The breaker has the performance of reliable seal, aging resistance, and flame resistance, explosion resistance,long mechanica life, simple installation and convenient debugging
