To investigate the destructive effect of ablation on epoxy resin insulation, we use argon arc welding to modify the surface epoxy resin with different values of ablation current, time, distance and area so as to obtain samples with different ablation situations. The surface resistivity and surface flashover voltage of the samples are then measured. The results show that the insulation property of the epoxy resin after high temperature ablation degrades greatly. Scanning electron microscopy and energy spectrum analysis indicate that the increasing surface roughness and oxide would reduce the insulation property of epoxy resin., authors=ZHAO Weikang^1,2,3, XU Rong^1,3, YUAN Weiqun^1,3, YAN Ping^1,3, authorsList=ZHAO Weikang, XU Rong, YUAN Weiqun, YAN Ping, authorCompany=1.
