Rancang Bangun Isolator Post Berbahan Resin Epoksi, Silicone Rubber, Zinc Oxide (ZnO), dan Pasir Silika

Abstract

The selection of the type of insulator used in a distribution or transmission network needs to consider its mechanical and electrical characteristics. The use of Zinc Oxide (ZnO) nanoparticle filler, silicone rubber and silica sand aims to increase resistivity, dielectric strength and AC high voltage resistance. This research discusses the design of insulators using 10 samples of epoxy resin main material and a mixture of silicone rubber, Zinc Oxide (ZnO) and silica sand to see how the effect of mixed materials on resistivity, dielectric strength of insulator material and leakage current in insulator equipment. From the results of the study, the highest resistivity value occurred at a surface resistivity of 5.699 GΩ and at a volume resistivity of 0.651 GΩm in the S10 test sample. The largest dielectric strength value is 94.6 kV in test sample S10, while the smallest is 59.4 kV in test sample S1.
