| Abstract: | Theories and some main protection methods of lightning-caused breaking of insulation-covered conductors in 10 kV overhead distribution networks were introduced.The main designing,structure and technology of a new type of lightening protection hardware were put forward.High current heat stabiliazation test,lightning attack high voltage test and main frequency arc burning test were performed which concerned three technical characterisitics of lightening protection hardware.The results indicated that lightening protection hardware could meet the requirements of lightning-caused breaking of covered conductors in 10 kV distribution networks.The lightening protection hardware needs no maintenance and it is practical where towers cannot be connected to ground in city. |
