Abstract :
The silicone-based coating applied to 345 kV post insulators
in a substation on the shore of Long Island Sound has depolymerized
over a period of about 7 years although no in-service
failures have occurred. However, the increasing rate of depolymerization
suggests that the coatings will have to be renewed in the
near future. This paper reports comparisons of aging and material
properties for a number of RTV silicone insulator coatings and
measurements related to application of a new coating over an existing,
field-aged coating.
