Description
Summary:	This study aims to reduce leakage current on silicone rubber insulators contaminated with salt mist by utilizing a coal fly ash mixture. Endurance tests and optimization were conducted on silicone rubber insulators with coal fly ash filler from four different regions (FA SCB, FA PSC, FA PSB, and FA PJL) with thicknesses of2 mm and 3 mm. The test results showed that FA SCB provided the best results with the smallest leakage current at a composition of 60% for 2 mm thickness and 20% for 3 mm thickness. The optimization value was achieved at 37.4406% (2 mm) and 43.9175% (3 mm). FA PSC achieved the best leakage current at a composition of 40% for both thicknesses, with an optimization value at 41.0915% (2 mm) and 52.4023% (3 mm). FA PSB provided the best results at a composition of 40% for both thicknesses, with an optimization value at 40% (2 mm) and 49.6792% (3 mm). FA PJL showed the best results at a composition of 20% for both thicknesses, with an optimization value at 31.2207% (2 mm) and 63.2527% (3 mm). By optimizing the composition of fly ash in silicone rubber, the insulators can more effectively reduce leakage current due to salt mist contamination, enhancing the reliability of the insulation system's performance in medium voltage electrical applications. This study used endurance testing methods according to IEC 60060-3:2016 and salt mist contamination according to ASTM B117.
