HengFengYou High quality and safety vcb ZW7-40.5 outdoor high voltage
vacuum circuit breaker
The ZW7-40.5 outdoor HV vacuum 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. 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 mechanical life, simple installation and convenient
debugging.
Service conditions:
1. Ambient temperature: not higher than +40 °C, not less than -35°C
2. Altitude: not exceed 1000m.
3. Relative humidity: daily average of not more than 95%, month average of not more than 90%.
4. Earthquake intensity: not more than ten.
5. No fire, explosion hazard, serious filthy, chemical corrosion, as well as places of intense vibration.
