Effect Composition of Fly Ash Filler on Electrical Properties of Silicone Rubber Insulator Material

This article is an attempt to get the explanation of the insulating material of silicone rubber is cheap. Things done is mixing the silicone rubber with other material in the form filler are cheap and easy to obtain. Coal fly ash is one of the sources of material which allows used as a filler because this material has a very fine particle size and contains materials that have been and are being studied as a filler for silicone rubber insulators. This paper explains the study to determine the properties of silicone rubber filled with coal fly ash from different sources, namely from the Tonasa coal-fired power plant and the Barru coal-fired power plant. The parameters measured in this study are the parameters of electrical properties such as contact angle, relative permittivity, dielectric strength, volume resistivity, and surface resistivity. The results of this study indicate that coal fly ash from the Tonasa coal-fired power plant more feasible for use as a filler material of silicone rubber compared to coal fly ash from the Barru coal-fired power plant for its ability to increase the contact angle of hydrophobic, dielectric strength, volume resistivity and surface resistivity
