%X This paper presents the effect of natural aging upon the performance of the polymeric insulation materials made from Epoxy resins, Polydimethylsiloxane (PDMS), and Rice husk ash compound. The samples of epoxy resin insulation material consist of Diglycidyl Ether of Bisphenol A (DGEBA), Meta Phenylene Diamine (MPDA) as curing agent, and 325 mesh Rice Husk Ash (RHA) as filler, treated with variation of PDMS content. The research aims are to observe the Equivalent Salt Deposit Density (ESDD), critical leakage current, and flashover voltage on the insulation material surface that has undergone a natural aging. Experimental method was carried out through the following procedure. The samples were placed outdoor for natural aging test, outside the building of electrical engineering and information technology of Gadjah Mada University in Indonesia. Then the ESDD, critical leakage current, flashover voltage on the sample surface was measured every 2 weeks. The experiment results show that the performance of insulator material fluctuates during 52 weeks. The higher PDMS with RHA filler content the lower ESDD and surface leakage current. Furthermore the flashover voltage increases.
