Polimer of epoxy resin which is used as high voltageis insulating materials Diglycydylether of Bisphenol A (DGEBA)with Metaphynelyne-Diamine(MPDA) catalyst with ratio I:/. Thefiller are aluminium oxide from 10% - 50% and aluminium oxide+ silicone rubberfrom 10% - 50% with ratio 1:1. The insulating materials are given industry pollutant withfixed value 200 ml. The method is used by accelerated aging at the laboratory. The experiments use testing box to adopt the tropical climate for 96 hours with days and nights simulation. Every 12 hours is checked its characteristic. The characteristic which is checked is flashover voltage, leakage current, ESDD, and hydrophobic contact angle. The result of this research will gain the correlation ESDD value, aging time, filler composite 10 the value of;7ashover voltage, leakage current, and hydrophobiccontact angle. The value of/las hover voltage and hydrophobic contact angle will decrease every increase ESDD value, while leakage current will go up. Ultraviolet (UV) radiation on the specimen's surface from 0 hours to 96 hours with days and nights simulation may cause fluctuation on flashover voltage and leakage current following days and nights simulation. In general the value of theflashover voltage tends to decrease but leakage current increase. The flashover voltage epoxy resin with fiber glass filler generally is better than silica quartz and alumunium oxide. The leakage current characteristic of epoxy resin with silica quartz filler has the best resistance against UV influence than Alumunium oxide and fiber glass filler. The epoxy resin with fiber glass filler has better contact angle than epoxy resin with alumunium oxide filler and epoxy resin with silica quartz filler.
