High voltage composite insulator and method of making same

摘要: A high voltage composite member, such as a support insulator or bushing, comprises core and sheath of elastomeric material vulcanized to the at least one module having an external shed inner cylindrical surface predetermined normal diameter. The has circumferentially continuous bulges overlapping engaging ends hold permanently in desired location on sheath, being substantially free deforming stress. sealing provides sealed interface between sheath. method making member steps providing unvulcanized thereon, constant outside diameter, diameter which is less than expanding permit be slid over core, placing upon surface, sliding location, allowing shrink its applying heat vulcanize concurrently displace from within returns completely unexpanded form adjacent both thereof location. residual mechanical
