ABSTRACT:
An electrical insulator includes a pair of endpieces fixed respectively to opposite ends of a cylindrical support. Extruded elastomer insulation material forms annular fins about the support. Each end of the support is inserted into a tubular housing provided in each endpiece. The fins cover a transition surface of tapering shape elastomer rings joining the outside surface of an endpiece to an outside surface of the support. A tapering ring of extruded elastomer material of triangular cross-section backs up against a shoulder of a respective endpiece at the opening to the housing into which the end of the support is inserted. The transition surface is defined by the exterior of the tapering ring.
