Graduate School at Shenzhen, Shenzhen 518055, Guangdong Province, China ABSTRACT: Room Temperature Vulcanized (RTV) silicone rubber coating can prevent pollution flashover accident from happening, and it has been widely used in China. Lots of 1 sample insulators are taken down from transmission lines in Tianjin directly without cleaning, then the hydrophobicity RTV classes of samples are investigated and their electrical performances are compared with new RTV coated insulators [1-2] and porcelain insulators. Then Fourier Transform Infrared 20 80 RTV Spectroscopy (FTIR) is employed to investigate the inherent 1986 1 property change of coating and influence by pollution source. RTV Based on all results, the using life
