The study of the lifetime performance of polymeric insulator is often based on incomplete data. Researchers face challenges of not having long observation time to gather complete lifetime data in order to make prediction with certainty. In this paper, we are proposing to use the best fitting polynomial interpolation approach to determine the lifetime model and extrapolate information towards the age...
This study investigates the aging of high-temperature-vulcanized (HTV) silicone rubber insulator under multiple stress conditions. Silicone rubber specimens were subjected to accelerate degradation using an accelerated weathering chamber. The specimen was subjected to accelerated aging cycle in accordance to ASTM G154 cycle 4 for a total of 3000 hours. The aging cycle goes through a cycle of 70°C...
