The verification testing and application of an all-composite silicone rubber distribution deadend

Nonceramic distribution deadend insulators typically consist of a pultruded fiberglass resin core (FRP) with crimped or epoxy potted metal end fittings and a molded rubber housing. New technology has allowed for improved designs of distribution deadends, optimizing dry arc and leakage distances for constant section lengths. A patented fiber winding process, which is different from pultrusion and filament winding, has enabled new designs for lighter weight insulators. This paper discusses a distribution insulator design made with a new technique and the testing that was conducted to verify the integrity of the insulators.
