Product Detail

1. Product description of ZW32-12KV Outdoor Vacuum Interrupter/ACR

Our type of ZW32-12KV outdoor pole mounted vacuum circuit breaker(recloser) is developed by our company. We aim to bring customers high quality products with best price and help customers realize automatic power distribution.

Reclosers are used in overhead lines and in substations. Like circuit-breakers they are capable of switching normal and fault currents. They are equipped with sensors and controller being the protection and control device. In case of a temporary line fault, they can trip and reclose up to four times, thus avoiding longer network interruptions.

As outdoor devices they can be pole or structure-mounted and exposed to environment and weather. Extensive testing beyond the recloser standard has proven the suitability for application in various climates to ensure long service life.
