Abstract :
Higher flashover voltages of transmission line polymer insulators were found to be due to large ratio of shed to trunk diameter. This causes current density at the trunks to be very high and all the trunks get dried causing the applied voltage to the whole insulator divided and allotted to individual trunks. Similar effect was aimed by applying hydrophobic silicone rubber coating to the trunks of a porcelain long rod insulator. In this paper, investigation results of the contamination flashover voltages of porcelain long rod insulators coated with RTV silicone rubber coating on the trunks are presented
