ANALYSIS OF VARIATION OF COAL WASTE FILLING IN PHYSICAL, ELECTRICAL AND MECHANICAL PARAMETERS AS AN EPOXY RESIN ISOLATOR

Electrical Engineering

The insulator functions to separate two or more conductors and prevent the flow of current between the conducting wires to the tower pole. Many insulators have been developed, including insulators based on epoxy resin. In this study, theaddition of bottom ash to the base material of epoxy resin was analyzed for the value of physical, electrical and mechanical parameters. The test material used is epoxy resin mixed with silicone rubber and bottom ash, each of which has a variation of bottom ash composition with percentages of 10%, 15% and 20%. Parameters analyzed were contact angle testing as physical parameters, leakage current values as electrical parameters and tensile strength and hardness as mechanical parameters. The results of the contact angle test ranged from 1°-89° and had partially wet properties. The results of the leakage current test show that the percentage addition of bottom ash 10% has the smallest leakage current value of 7.985 mA. Meanwhile, from a mechanical point of view, the tensile strength and hardness tests have inverse characteristics,
