  • Method of manufacturing HVDC mass impregnated cable transition joint
    Patent number: 11876358
    Abstract: A method for creating a flexible transition joint between HVDC-MI cables having different diameters. The central wires of the conductors are thermally joined by a conical connection piece. The strands of the layers of stranded wires surrounding the central wires are rewound, cut and thermally joined along their respective lay lengths. The stranded are sanded/ground along the lay length of the strands to form a smooth uniform transition having the same slope as the conical connection piece. A paper lapping machine is used to form an insulation patch over the transition joint.

  • HVDC Mass Impregnated Cable Transition Joint
    Publication number: 20180375223
    Abstract: A method for creating a flexible transition joint between HVDC-MI cables (20/40) having different diameters. The central wires (24/44) of the conductors (22/42) are thermally joined by a conical connection piece (62). The strands of the layers of stranded wires (26) surrounding the central wires (2474) are rewound, cut and thermally joined along their respective lay lengths. The stranded are sanded/ground along the lay length of the strands to form a smooth uniform transition having the same slope as the conical connection piece. A paper lapping machine is used to form an insulation patch (72) over the transition joint (69).
