Abstract

This study aims to determine the breakdown voltage value of silicon rubber (SiR) insulation which is given a mixture of natural rubber (NR). The test was carried out using SiR samples and SiR + NR samples with different concentrations and had a size of 50 mm x 50 mm with a thickness of 1 mm. The test was carried out using a needlefield electrode system with alternating high voltage at the gap between the sample surfaces and the needle tip diameter of 4.9 x 10-17 mm. The test results show a significant effect of mixing silicon rubber (SiR) and natural rubber (NR) on the insulation strength of silicone rubber (SiR) in resisting stress stress. The test results showed that mixing silicon rubber (SiR) with natural rubber (NR) was able to increase the dielectric resistance of the sample to withstand the given mechanical stress. The increase in breakdown voltage of silicon rubber (SiR) insulation when given a mixture of natural rubber (NR) with concentrations of 10%, 15%, and 20% was 4.66%, 9.84%, 5.58%. The average breakdown voltage of 100% silicon rubber (SiR) insulation is 3.40 kV. From the results of these measurements indicate that mixing silicon rubber (SiR) and natural rubber (NR) with a concentration of 15% has the highest breakdown voltage value than other concentrations. Key words: breakdown voltage, silicone rubber (SiR), natural rubber (NR)
