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.
Ambient temperature: upper limit +40ºC, lower limit -40ºC.
Altitude: divided into 1000m conventional type and 2000m plateau type two.
Wind pressure: not more than 700Pa (wind speed less than 35m/s).
Seismic cracking: not more than 8 degrees.
Installation site: There should be no fire, explosion danger, serious pollution, chemical corrosion and violent vibration
