Description
ZW8-12 series outdoor high-voltage vacuum circuit breaker is a kind of three-phase outdoor high-voltage switchgear of rated voltage 12kV and AC 50Hz.
Its population structure is three-phase together box type. Three-phase vacuum arc-extinguish chamber palaces in a metal cabinet, using the SMC insulating material to insulate inter-phase and phase to earth, which is reliable in performance and high in insulating intensity.

ZW8-12G is combined with ZW8-12 circuit breaker and isolating sword, called combination circuit breaker and used as a section switch.
Applying ambient conditions
1.Ambient temperature:-10ºC~+40ºC.
2.The height above sea level:≤1000m(besides the special requirements).
3.Relative humidity:the average humidity of a day should be no more than 95%;the average humidity of a month should be no more than 90%.
4.Saturated vapour pressure:the average pressure of a day should be no more than 2.2kPa;the average pressure of a month should be no more than 1.8kPa.
5.Earthquake intensity:not exceed 8 degrees.
6.It should be installed in the places without fire,explosion,serious filth,chemical erosion and violent vibration.
