Impacts of Terminal Treatment Methods on Lightning Insulation Characteristics of Insulated Overhead Line
Practical application experience shows that the terminal of insulated overhead line is easy to be broken by lightening.In this paper,the lightning simulation tests for different termial treatment methods were conducted on overhead insulated wires,and the impacts of the various terminal treatment methods on lightning insulation characteristics of insulated overhead line were researched based on isothermal relaxation current method.The analysis of the aging factor indicates that the aging factors of insulated overhead line terminals would rise after lightening test,the sign of insulation degradation.Besides,due to the lightning arc movement and moisture,using 3M adhesive tape sealing after stripping can improve the insulation property after lightening test.
