CA 2151352

A composite insulator includes a FRP core rod and a sheath which is formed by integrally molding an insulating polymeric material to cover the core rod over substantially the entire length thereof. The sheath is composed of a plurality of molded portions which are aligned with each other in the axial direction of the core rod. Adjacent molded portions of the sheath are arranged relative to each other so that a gap is left between the opposite ends of the molded portions. The gap is filled by a joint insulating material which is integrally united to the polymeric material of the adjacent molded portions.

Isolateur composite comportant une armature en plastique renforcé de fibres de verre et une gaine formée par moulage intégral d'un polymère isolant recouvrant l'armature sur toute sa longueur. La gaine se compose d'une pluralité de parties moulées alignées les unes sur les autres dans la direction axiale de l'armature. Certaines parties adjacentes formant la gaine moulée sont disposées de manière à laisser un écartement entre les extrémités opposées. L'écartement est rempli de matériau de jointoiement isolant qui devient partie intégrante du revêtement polymère.
