摘要：

SiR (Silicone rubber) composite insulators are widely used in China due to their characteristics like excellent anti-polluting-flashover performance, lighter weight, easy transportation and installation. In addition to HTV (high-temperature vulcanized silicone rubber) and RTV (room-temperature vulcanized silicone rubber), LSR (liquid silicone rubber) material is increasingly used for high voltage external insulation in recent years. Outdoor insulators are exposed to long-term sunlight. UV (ultraviolet) radiation may cause the fracture of silicone rubber, the changes of internal structure, even oxidation and degradation reactions. Therefore, the aging characteristics of LSR under UV radiation is very noteworthy, where there is still a lack of research. In this paper, 1000h continuous aging were conducted using accelerated UV aging apparatus. The changes of static contact angle, hydrophobic transfer ability and Shore hardness during the test were measured, and fitting formulas were given. Besides, the micro-physicochemical characteristics were analyzed by FTIR and XPS. Finally, UV aging results of LSR and HTV were compared.
