Abstract

High voltage resistant integrated member is made by extruding a sheath (2) of ethylene-propylene-diene copolymer, ethylene-propylene copolymer, or butyl rubber elastomer onto a core (1) at a temp. below its vulcanisation temp. At least one fully vulcanised elastomeric shed (5) of the same or similar elastomer as the sheath is mounted on it then the assembly is heated to vulcanise the sheath and bond it to the core and the shed. Mounting of the sheds is facilitated by expanding them at room temp. then cooling them while maintaining the expansion, the sheds shrinking tightly onto the sheath covering core on warming. Pref. at least one metal fitting is mounted on the core and sealably secured prior to vulcanisation of the sheath so that fitting is bonded to it.
