ZW27-22 outdoor AC vacuum circuit breaker is an outdoor high-voltage switchgear with a rated voltage of 12kV and three-phase AC 50Hz. Mainly used for breaking and closing load current, overload current, and short-circuit current in power systems.

ZW27-22 outdoor vacuum circuit breaker is suitable for protection and control in substations, industrial and mining enterprises, as well as urban and rural power grids. It is particularly suitable for places with frequent operations and urban network automation distribution networks.

ZW27-22 Outdoor Vacuum Circuit Breaker Product Features:

1. Use a vacuum arc extinguishing chamber.
2. Adopt air silicone rubber and engineering plastic composite insulation.
3. Voltage transformers can be installed inside the switch to provide operational power and voltage sampling.
4. The plan is flexible and can reserve interfaces for automatic distribution, facilitating the development of distribution automation.

Structural features: (P17)

1. Use a vacuum arc extinguishing chamber to extinguish the arc.
2. Using air? Silicone rubber and engineering plastic composite insulation avoid the possibility of insulation accidents caused by oil degradation in oil insulation.
3. Combined with the controller, it can be used as an automatic recloser or automatic segmenter.
