Abstract :
Room temperature vulcanized silicone rubber (RTV-SR) is widely applied to outdoor insulation in power system. It is aged under the conditions of outdoor environment. Temperature is one of the ageing factors. So the resistance to high and low temperature of RTV is important to its ageing performance. In the paper, two kinds of RTV nanocomposite are achieved, and the resistance to high and low temperature is tested with the help of TG (thermogravimetry)/DTG (differential thermogravimetry) and DSC (differential scanning calorimeter). The decomposing temperature and glass transition temperature of RTV nanocomposite are obtained. The test results show that RTV nanocomposite has better resistance to both high and low temperature, which may lead to better ageing performance of RTV material. The mechanisms are also discussed.
