EFEKTIFITAS PEMANFAATAN PASIR PANTAI BERKALSIUM TINGGI SEBAGAI MATERIAL PENGISI BAHAN ISOLASI RESIN EPOKSI UNTUK ISOLATOR LISTRIK
ABSTRACT: Insulation materials
that commonly used in air insulation, which, is operated at high voltage, are
the porcelain, glass, and polymer materials. One of the insulating polymer
materials that are used is epoxy resin because it has several advantages
compared to that. However, this insulation material has a degradation of the
surface due to environmental and cause insulation coated with dirt and
chemicals in the long time.
Material that was used in this research was epoxy resin polymer isolation
using of comparison values (base material diglycidyl ether of bisphenol-A:
hardener material metaphenylene diamine) were 1:1, with the increase of silane
and high calcium coastal sand as filler by the value of 10%, 20%, 30%, 40%, and
50%.
Research was done in laboratory according to standard IEC 587: 1984. In
this study, the effect of variation in stoichiometry to the hydrophobic contact
angle value, leakage current waveforms, and surface degradation caused by
erosion and tracking processes and tracking time were analyzed.
From the results of the research, it was obtained that the epoxy resin
that was used in this research are categorized as hydrofobik and partially
wetted. The increase concentration of silane dan high calcium coastal sand as
filler caused the increase in contact angle which meant the increase in surface
insulation resistance, so that leakage currents flew on the surface not easily
and slow down the aging or the degradation decreasing on the surface of
insulating material. Concentration value of filler that had the optimal
performance of the tracking process and erosion was 40%.
