| Abstract: | A new arc-protection hardware with stabs is developed based upon experimental researches on lightning impulse flashover tests, pressing force and heat stabilization tests, as well as power frequency arc tests. This hardware can position the path of lighting-flashover and make the root of power frequency-arc departed from insulation-covered conductors. Therefore, the breakage of insulation-covered conductors caused by lightning stroke can be avoided. |
