EXPERIMENTAL STUDY A ND THERMAL EFFECT ON SUSPENDED INSULATORS WITH ALUMINOUS PORCE LAIN

The suspension insulators are subjected on transmission line for a long time, in service. Long - term reliability of the insulators depends on both mechanical and electrical performance. This study described the thermal performance testing by heating process and thermal mechanical performance test methods on alumina porcelain insulators which are used for transmission lines. There are three types of testing with variable electrical load such as 1000watts, 2000 watts and 3000 watts, which are applied on suspen sion insulators by using of alumina porcelain coating material
