Introduction:

ZW32-12 Model Outdoor Pole-mounted High Voltage Vacuum Circuit breaker is mainly used to breaker and close load current overload current and short-circuit current in substation, industrial and mining establishments, and urban rural distribution network as a protection and control equipment. Especially suitable for occasions with frequent operating and automatic urban distribution network.

Normal working environment 1 Ambient air temperature : -40 to 40; daily temperature difference : 25 ;2 Altitude :≤2000m (if the place is at higher altitude , enhance rated insulation level , it should be custom-made for 2000m );3 Wind pressure : ≤700Pa(Equivalent to wind speed 34m/s);
