Definitions

  • the subject of the present invention is a rigid electrical insulator of the base or rod type, the lower end of which is fixed to the said base or the said rod and the upper end of which has at least one groove intended to receive an electric cable, characterized by the fact that it includes at least one rod central in glass fibers agglomerated by a resin fixed at its lower part to said base or to said rod, and at its upper part to a rigid overmolded head provided with at least one groove, the external face of said rod and said rigid head being tightly covered by a coating, that of said head being made of flexible insulating elastomer and that of said rod being chosen from elastomers, resins and varnishes, said groove provided with its coating defining said groove.
