Abstract
In a cable stub assembly (20) which is used to interconnect two cables (22 and 24), at least one of which is pressurized with a gaseous medium, a portion of a plastic jacket is removed from an interior portion of a length (31) of cable to expose conductors (33--33) of a core (32). Heat shrinkable sleeves (61 and 66) each of which comprises an irradiation cross-linked polyolefin material are positioned over the jacket of the cable on each side of the interior portion from which the jacket has been removed. The heat shrinkable sleeves are caused to contract about the cable jacket. Inner surfaces of the sleeves are coated with an adhesive material which is helpful in providing a sealed engagement of the sleeves with the jacket. A length of tubing (81) is disposed about the cable jacket and the contracted sleeves. A polyurethane filling material (82) is introduced into the tubing and is adhered sufficiently to the sleeves to prevent substantially the escape of the gaseous medium from the at least one cable. In the event that the cable includes a metallic shield (37), grounding clamp connections are made to the shield on each side of the exposed conductors. A plastic tape (58) having an adhesive coating is used to prevent the egress of the gaseous medium where a post (56) of each grounding clamp extends through an associated sleeve.
