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. 
The circuit device is small, Weight light, anti-condensation, maintenance-free features, can adapt to poor weather Condition and dirty environment. .
Overview
 1. The complete specification of VMD series vacuum circuit breaker can meet customers' different needs.
 2.  VMD adopts the latest embedded poles and low-resistance vacuum interrupter.With main conductive circuit sealed in epoxy resin, the insulation performance will be more stable.
 3. VMD employs an accurate gear driving system, instead of the traditional chain wheel driving system. 
 4. VMD series circuit breaker passed Type Test Report according to GB and IEC standards.
 5. VMD series circuit breaker has exported to 26 countries and regions in the world.
