Abstract :
An aged silicone polymer insulator, which had been used at testing station near sea coast for approx. 10 years, was investigated. The aging mode was different from erosion. It was confirmed that the rubber aging phenomena was similar to damage due to nitric acid by FT-IR analysis. It is deemed that the acid was generated during corona discharge on rubber housing. In order to avoid such a rubber aging, it is important to minimize corona discharge even under wet conditions.
