To investigate the temperature distribution on the surface of a silicone rubber exposed to partial arc discharges，experimental and numerical analyses on thermal characteristics were carried out. Tests were executed by placing the salt-waterlogged glass-filter paper on a silicone rubber sheet to simulate a polluted electrolyte layer. The results showed that the formation heights of arc channels from the surfaces of silicone rubbers and temperature distributions varied with the electrolyte conductivity. The temperature distribution on the specimen surface became high in the middle of the discharge gap while those became low at points of contact between an arc discharge and tips of glass-filter paper. The thermal diffusion from the points of contact between the arc discharge and the tips of glass-filter paper into electrolyte electrodes caused the temperature decrease at the points.
