Routine tests of composite insulator with voltage greater than 1000V in IEC 61109 2008

Last time we talked about sample test of silicone composite insulator for AC system above 1KV, the IEC 61109:2008 has defined it clearly. Today let’s the coming section”routine test” of polymeric insulator in this IEC 61109: 13 Routine tests 13.1 Mechanical routine test Every insulator shall withstand, at ambient temperature, a tensile load at RTL […]
