  • Patent number: 11201458
    Abstract: A joint, termination or cross-connection arrangement for a cable includes a first cable and a protective casing. The arrangement further includes a transition sleeve. The transition sleeve, at a first longitudinal end surface thereof, is welded to the metallic sheath of the first cable around the whole circumference of the metallic sheath. The transition sleeve is furthermore welded to the protective casing around the whole circumference of the transition sleeve. A method of providing such an arrangement includes: welding the transition sleeve, at the first longitudinal end surface, to the metallic sheath of the first cable around the whole circumference of the metallic sheath; and welding the transition sleeve to a first tubular end portion of the protective casing around the whole circumference of the transition sleeve.

  • Publication number: 20190190245
    Abstract: The disclosure relates to a joint, termination or cross-connection arrangement for a cable. The arrangement includes a first cable and a protective casing. The arrangement further includes a transition sleeve. The transition sleeve is welded to the metallic sheath of the first cable. The transition sleeve is furthermore welded to the protective casing. Thereby, a water tight connection between the metallic sheath of the first cable and the protective casing is achieved without the need for used of lead containing materials. The disclosure further relates to a method of providing such an arrangement.
