초록
The NGK suspension insulators are subjected in harsh environments in service above 40 years long time. The long term reliability of the insulators is required for both mechanical and electrical performances. This study describes some electrical performances according to KEPCO-standard. There was fail in electrical and mechanical performance test such as galvanizing, low-frequence wet flashover voltage, puncture and combine mechanical & electrical strength test. The NGK suspension insulators of 1968 were shown lower electrical and mechanical performance than those of 1979.
