Description
ZW43-12 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.
ZW43-12G is combined with ZW43-12 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.
ZW43-12 model outdoor vacuum circuit device (hereinafter referred to as circuit device) is Rated voltage 12KV, three-phase AC 50/60Hz outdoor distribution equipment. And Short-circuit current. For the main break, when closing the power system load current, overload current And Short-circuit current. ,And industrial and mining enterprises in the substation for power distribution system for the protection and control purposes, And frequent operation of rural power grid places.Â
