Abstract

Ultra High Voltage (UHV) and Extra High Voltage (EHV) overhead power lines require line insulators that are light in weight and have a good performance under severely polluted ambient conditions. Polymeric or composite insulators are light in weight as compared to the conventional ceramic or glass insulators. Polymeric insulators are also found to have a much better electrical performance than the ceramic or glass insulators in wet and polluted conditions since it is more hydrophobic in nature. In the present study, nanodielectric based novel composite insulator materials have been studied for their tracking and erosion performance under polluted conditions. Here the base polymer selected is silicone rubber (SR) which is normally used as the weathershed material. In this paper, tracking and erosion performance of micro composites of alumina trihydrate (ATH) with silicone rubber as the base material is compared with nano composites of ATH as well as micro and nanocomposites of aluminium nitride (AlN).
