Abstract :
Aging and estimate of useful life of polymer insulators installed in field is a major concern nowadays. In order, to find the extent of aging and useful life of polymer insulators, the effect of UV radiation, temperature, salt fog, electric stress, low pressure, nitric acid, clear sunshine and humidity were seen; by exposing the HTV silicone rubber insulators to these parameters in laboratory. After these experiments, the samples were analyzed with material testing techniques and were visually observed to locate any noticeable change
