GW□ -12 outdoor high voltage isolating switch
Product Details
Product overview
GW□ -12 outdoor high voltage isolation switch is suitable for power system with frequency of 50Hz and rated voltage of 12KV. The switch device is on the outdoor high-voltage power distribution equipment line for the line to open and close the circuit when there is voltage and no load. Among them, the pollution flashover problem occurs during the operation of the pollution-proof isolating switch. The switch has three-pole linkage, good contemporariness, and is equipped with an orphan guiding device, equipped with a middle spring, which can realize rapid opening and closing. It has the advantages of breaking and closing small inductance and capacitance current.
