Abstract

This paper describes research on the effect of the amount of filler (fly ash) in high voltage insulator material of silicone rubber for its electrical properties. Fly ash is used as a filler material because this material is cheap, readily available, and efforts to utilize waste from coal fire power plants. Tests conducted on various amounts of fly ash that is loaded in silicone rubber. The test material is made in 4 (four) forms of FA20, FA30, FA40 and FA50. The electrical properties were measured in the form of relative permittivity, dielectric strength, and surface resistivity. The standard used in this study is ASTM standard. The results of this study indicate that the value of the relative permittivity of silicone rubber increases with increase of filler quantity (fly ash), but decreased after aging. Likewise, increased quantity of fly ash on the silicone rubber made the breakdown voltage and the surface resistivity becomes larger.
