In any power transmission system, insulators are essential for a reliable electrical power supply. The Efficiency of
insulators will be decided by their electrical and mechanical properties. Recently in many of the power transmission systems, the
conventional porcelain insulators are being replaced by polymeric insulators due to various advantages in their properties.
Polymeric insulators have been increasingly popular in recent years as a result of their superior performance in contaminated
environments due to their hydrophobic nature.
