ZW8-12 Series Outdoor High Voltage Vacuum Circuit Breaker

Product Overviews

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,mainly used for making and breaking the load current, overload current and short-circuit current in power systems. It is applicable to transformer substation, industrial and mining enterprises as well as urban and rural power grid systems for protection and control. 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.

Operator of the series is CT23 type spring energy-storage operator, divided into electric kind and manual type.

Working Conditions

1. Altitude: ≤1000mm;
2. Ambient air temperature: -35℃ ~+40℃ ;
3. Wind speed: ≤34m/s;
4. Earthquake intensity:8 degree;
5. Relative humidity: monthly average ≤90%, daily average ≤95%;
6. Ice thickness: 10mm ;
7. Pollution degree: IV;
8. There will be have dew under the condition of high temperature low down hastily.

Product Feature of ZW8-12 Outdoor Vacuum Circuit Breaker:
1. Vacuum arc extinguish.
2. Silicon rubber and plastic composite insulation.
3. It can be matched with controller as auto-recloser and auto-sectionalizer.
