Outdoor Vacuum Breaker
Product Description
ZW32-40.5 outdoor high-voltage vacuum circuit breaker adopts a unique design of integrated sealed pole and high-reliability operating mechanism.The device is mainly used in medium voltage overhead power gird,as a sub-combined with load current,overload current and short circuit current.
Features
ZW32-40.5 outdoor high-voltage vacuum circuit breaker is mainly composed of integrated sealed pole,current transformer,operationg mechanism and box body. This type of circuit breaker is miniaturized,and its shell is made of high-quality steel box.Current trasformers can be selected according to users' needs. ZW32-40.5 outdoor high-voltage vacuum circuit breaker and matching intelligent control combination.On-off operation of switch can be realized locally,and it can also be operated by remote control through communication interface.Other information of the circuit breaker can also be transmitted to the control center,and the communication channel can be cable,optical fiber.GPRS/CDMA,GSM,etc.
