Abstract

A Z-shaped sealed cable conductor of a high-voltage direct-current submarine cable and a design method thereof. The cable conductor comprises a center wire and a plurality of single wires, the plurality of single wires are stranded on an outer wall of the center wire in a layer-by-layer overlapping manner, the single wires are Z-shaped single wires, every two adjacent Z-shaped single wires are mutually stacked and matched end to end, the plurality of Z-shaped single wires are spirally and tightly wound together by means of a stranding process, and chamfers are provided at corners of the Z-shaped single wires. The Z-shaped sealed cable conductor of the high-voltage direct-current submarine cable uses a Z-shaped single-wire circular pressing structure, the problem of high pressing difficulty of a frame stranding machine is effectively solved, a conductor pressing coefficient is higher than that of a circular single-wire circular pressing structure, and the requirement for the water blocking performance of the conductor during high-sea laying of the high-voltage direct-current submarine cable can be satisfied.
