Abstract The insulated cable splice joins the end portions of a metallic conductor by positioning the end portions in a metallic sleeve in overlapped relation to each other and the sleeve is deformed to frictionally engage the metallic conductor end portions. The surface of the cable adjacent the exposed end portion of the metallic conductor is buffed and thereafter the exposed end portions of the conductors on opposite sides of the metallic sleeve are helically wrapped with a tape to compress the conductor strands adjacent to the edges of the cable insulation. The recessed portion in the splice formed between the edges of the cable insulation is filled with an elastomeric filler material, preferably by helically winding a strip of elastomeric filler material over the exposed conductor end portions and the metallic sleeve. The outer surface of the filler material has a diameter slightly larger than the diameter of the sheath of insulation on the conductor. A liquid cement is applied to the outer buffed surface of the cable insulation and over the filled recessed portion between the edges of the cable insulation. A strip of elastomeric tape is helically wound in overlapped relation around the outer surface of the cable insulation and the helically wound elastomeric tape extends for preselected distances on opposite sides of the metallic sleeve. A portion of the cement applied on the surface of the cable insulation remains exposed beyond the ends of the tape winding. Thereafter, a plurality of elongated strips of flame and abrasion resistant tape are positioned longitudinally on the cable insulation in overlying relation with the helically wound elastomeric tape. The strips of flame and abrasion resistant tape are arranged with the side edges in overlapped relation to provide a water resistant splice. Strips of flame and abrasion resistant tape are helically wound about the end portions of the longitudinal strips and over portions of the cable insulation having the exposed layer of cement thereon to seal the ends of the splice. The above described helically wound elastomeric tape and plurality of strips of longitudinally positioned abrasion resistant tape may also be employed to repair damaged insulation on a cable where the conductor does not require splicing.
A cable splice comprising, a metallic sleeve member extending over overlapped conductor end portions, said metallic sleeve member being deformed to frictionally engage the conductor end portions and forming a recessed portion between the edges of the cable insulation, said recessed portion having an elastomeric filler material positioned therein between the edges of the cable insulation and around the metallic sleeve member and the conductor end portions, said filler material having an outer surface with a diameter slightly larger than the diameter of the cable insulation, elastomeric filler tape positioned over the cable insulation and the elastomeric filler material, said elastomeric filler tape being helically wound in overlapped relation, elongated strips of abrasion resistant jacketing tape positioned longitudinally on the elastomeric filler tape with the side edges of side elongated strips in overlapped relation, and other strips of abrasion resistant jacketing tape helically wound about the end portions of said overlapped elongated strips to provide moisture resistance for the splice end portions.
