## Abstract
Polymer insulators are one of the important components in the distribution of electric power systems that function to separate active and inactive parts. Polymer materials have advantages in the form of better dielectric properties, volume resistivity and thermal properties, and are resistant to water (hydrophobic). However, polymer insulators are susceptible to extreme temperatures and the mechanical strength of polymer insulators is still lower than ceramic and glass insulators. To overcome this problem, silica (SiO2), titanium (TiO2) and ATH fillers are added to silicone rubber elastomers which can increase resistance to ultraviolet (UV) exposure, increase mechanical strength, and increase resistance values to leakage currents. The purpose of this study was to determine the effect of a combination of ultraviolet aging factors and humidity on the decrease in hydrophobicity and breakdown voltage of silicone rubber polymer insulators. This study was conducted by aging testing in a chamber with a given temperature, humidity, UV light, and electric field loading. To determine the dielectric properties of the sample, measurements were carried out for each cycle (24 hours) where the measurements carried out were in the form of weight measurements, contact angles, permittivity, surface resistivity and volume resistivity. There are several supporting parameters measured to see the reliability of the material, namely the breakdown voltage test, FTIR, and tensile strength. From this study it was found that the addition of filler concentration does not always have a positive effect on the mechanical behavior of silicone rubber. The lower the weight of the material, the lower the relative permittivity value obtained, but the relative permittivity obtained tends to be greater. Other results obtained are that the greater the percentage of sample absorption, the smaller the contact angle obtained, but all contact angle values obtained are all classified as water repellent (hydrophobic).
