The development of room temperature vulcanized (RTV) silicone coatings in China began in early 1985. Over the course of time, they have come to be widely used in China. At present, nearly 800,000 kg of RTV coatings are used every year. They have successfully prevented serious pollution flashover of traditional glass and porcelain insulators and radically reduced the costs of maintaining transmission...
Aiming at the problem that silicone rubber (SIR) is used in different environmental areas in China, present paper reports the hydrophobicity transference of SIR affected by pollutions and environmental factors. Kieselguhr and kaolin were used as artificial pollutions, and then the hydrophobicity of SIR was found to be affected by the content of soluble salts, and non-soluble pollutions. According...
The usage of silicone rubber insulators in various contaminated areas has increased prominently in recent years in China, and it still keeps this increasing trend. As the energized time in the field is prolonged, the change of hydrophobicity and the accumulation of pollution directly affect the electrical insulation performance of composite insulators. This paper reports the electrical insulation...
