ZW6-12 Outdoor High Voltage Vacuum Circuit BreakerDetailed product description：

main purpose
1、 ZW6-12/630 outdoor high-voltage vacuum circuit breaker is suitable for use in three-phase AC 50HZ, rated 12KV power grids. It is used for dividing and closing load currents, overload currents, and closing and breaking currents, and can also be used as a section switch for 12KV urban or rural power grids.
2、 This product operates in a reclosing state and, when equipped with a suitable control system, can be used as a recloser or segmenter in power lines.
3、 It can be independently applied to small and medium-sized substations, with the characteristics of reducing land occupation and saving investment.
4、 Whether used in power lines or in substations, there are smart units that can be equipped with grid automation and PW to achieve local and remote control.
Usage environment
1、 Surrounding air temperature: upper limit of 40 ℃, lower limit of -40 ℃;
2、 Altitude ≤ 2000m;
3、 Wind pressure: not exceeding 700pa (equivalent to a wind speed of 34m/s);
4、 The earthquake intensity shall not exceed magnitude 8.
