| Abstract: | The lightning-caused breaking failures on 10kV overhead lines have serious impact on the safety of power supply in the construction of applying insulated conductors on power distribution lines. By analyzing the lightning-caused breaking mechanism of insulated conductors, this paper introduces installing metal oxide transmission line arresters which can prevent power distribution lines effectively arising damages from lightning over voltages. And it can limit the lightning-caused breaking failures of insulated conductors occurring to ensure the safe operation of insulated distribution lines. At the same time, the possible problems of lightning protective technology of installing transmission line arresters on power distribution lines are indicated, and the installing density and protective effect of transmission line arresters are analyzed, too. |
