GW¨-12、GW¨-40.5 series outdoor high-voltage isolation switch(hereinafter referred to as isolating switch), is a company based on the original products through design updates, so that structure is more reasonable and more reliable operation. This applies to switching frequency 50Hz, rated voltage of 12KV or 40.5KV power systems. In outdoor high-voltage power distribution switchgear equipment, line for line voltage in a no load to open and close the circuit, of which anti-dirty filthy isolating switch users in the region to meet the heavy demand, which can effectively solve the isolation switch in operation appears flashover problems. Switch three-pole interaction, over the same period is good, with Guo in the spring, enabling fast together=this switch with similar products, compared withan open cut, closing small inductor and capacitor current advantage.
