Summary:

 

GW1-12; 40.5/630-20 outdoor AC high-voltage disconnector (hereinafter referred to as disconnector) is a new product of our company, which has been designed and updated to make the structure more reasonable and the operation more reliable. The switch is used in power system with frequency of 50 HZ and rated voltage of 12 KV or 40.5 KV. Switching device is used in outdoor high voltage distribution equipment line for line miscellaneous voltage, no load is used for switching on and off circuit, among which anti-pollution isolation switch meets the dirty area, and can effectively solve the problems of isolation switch in operation. The switch has three poles linkage, good periodicity, and can be equipped with arc-starting device, with over-middle spring, which can realize quick opening and closing. Compared with similar products, the switch has the advantages of switching off, closing small inductance and capacitive current.
