Influence of the Filler Treatment on Dielectric Properties of Silane Epoxy Resins in Tropical Climate

The specimens of silane epoxy resins insulating materials are based on diglycidyl ether of bisphenol-A, cured with metaphenilene-diamine, with stochiometric value of unity, and 325-mesh silica filler treatment. Silane epoxy resins are the name of new thermosetting polymeric insulation materials that have been developed, with the materials composition was obtained from the experimental research. The amount of six types variation of the silane in the room temperature vulcaniced, compare with the six types variation of the filler without silane treatment. The study towards improving the performance of the epoxy resins is conducted, by adding silane treatment as filler, and a new performance in regard with hydrophobicity is realized. Experimental methods for 12^th types of specimens was carry out through the following procedure, the specimens are installed, on the Parangtritis natural aging test, site located plusmn30 km in the South of Yogyakarta for 60 weeks, and the performance observation every two weeks. This site is subjected to heavy coastal pollution as well as to high sunny levels. The observed performances from experimental methods as follow, flashover voltage, leakage current on surface, equivalent salt deposit density, and the contact angle of the hydrophobicity. The result of experiment indicated that the silane treatment of the filler can be improve overall electrical performance of the RTV epoxy resins silane, compared to the RTV epoxy resins without silane
