ZW20-12 Outdoor Pole-mounted Vacuum Circuit Break is an outdoor HV switch device with rated voltage of 12kV, three-phase AC frequency of 50Hz, opening and closing load current, over-current and short circuit current.

It is applied in substation, industrial and mining establishment and urban and rural grid as a protection and control device, especially in the places of frequent operation and in the distribution automation grid in the urban.

This product meets the standards of GB1984-2003 and DL402-2007.

1. Best choice for the reconstruction of urban and rural grid：it can work with controller to achieve the function of remote control, metering, signaling and regulation.

2. Easy and convenient to operate: energy-stored type, it can open and close manually and electrically. It has the function of manual energy storage, opening and closing, available for operation at a short distance.

3. Excellent breaking capacity:  short-circuit breaking current 25kA, 30 times. 

4. Small operating power and high reliability: the operating power of new design of small electric spring actuator reduces to minimum, about 30W.

5. Flexible installation: by lifting or supporting with brackets.

6. Reliable sealing performance: the SF6 gas pressure gauge reaches zero and it adopts the technology of mature sealing structure, not easy to leak.

7. Unique way of cable in and out: it uses silicone rubber tube, leaving enough insulation distance between terminals, good outer insulating performance.

8. Safe operation: there is an explosion proof device on the top of the frame. No leakage of high temperature gas or spatter even if there is an internal fault.
