Abstract

While all materials age (and/or degrade) over time, high voltage outdoor polymeric insulators do more so since they are mostly organic materials that contain inorganic fillers. Long term (thousands of hours), multistress, accelerated aging of polymeric insulators in the laboratory under conditions simulating the actual stresses encountered in the field permits a better understanding of the ongoing mechanisms related to aging and life expectancy of these materials. This article presents the multistress aging studies of 28 kV silicone rubber polymeric insulators under east and west coasts of USA.
