Many researches about silicone rubbers which are applied to materials of outdoor insulators and bushings have been conducted. Recently, As nano technologies have been developed, nano fillers are added to electrical materials to improve mechanical and electrical performances. In this paper, Room Temperature Vulcanizing(RTV) silicone rubber nanocomposites was studied about electrical performances and hydrophobicity recovery under the AC electrical stress and contamination. Silica and ATH was added as nano fillers, and specimens was contaminated by a dipping method. Flashover voltage and contact angle was measured. As a result, Nano filler improved electrical performances, and not reduced the hydrophobicity recovery.
