Abstract
An adaptor for placement at the terminus of an electrical power distribution cable having diametral dimensions falling within a given range of sizes, the cable being of the oil-filled type including a conductor, a paper insulator and a lead jacket, to seal the terminus and enable installation, in the field, of an electrical connector for use in an electrical power distribution system. The adaptor includes a sleeve portion of insulating material for placement over the cable insulation, a conductor-sealing portion for receiving the conductor of the cable, a jacket-sealing portion for juxtaposition with the lead jacket to seal the juncture between the lead jacket and the adaptor, a dielectric filler for placement between the cable insulation and the sleeve portion, and an electrical stress control member for controlling electrical stress along the interface between the cable insulation and the dielectric filler.
