Abstract :
Weathering polymeric insulators in the lab under environmental conditions, similar to that experienced in the actual field, has the merit of simulating the actual service environment in the lab. This permits a better understanding of the ongoing mechanisms related to aging and longevity of insulators. This paper presents the results of a one year environmental multistress aging study of polymeric insulators in a US Northeast coastal environment. Weather cycles simulating summer and winter weather conditions were developed based on Boston data. Field aging was also done for one year. Field and lab aging correlate well exemplifying the validity of the multistress weathering performed in the lab
