Document Type and Number:
WIPO Patent Application WO/2022/134392
Kind Code:
A1
Abstract:
Provided are a submarine cable and a manufacturing method therefor, relating to the technical field of cables, and being used for solving the technical problems of the poor bendability, flexibility and electrical performance of submarine cables. The submarine cable comprises a submarine cable segment and a landing cable segment, wherein the submarine cable segment comprises a first conductor; the first conductor comprises n layers of first monofilament layers; the landing cable segment comprises a second conductor; the second conductor comprises m layers of second monofilament layers; the m layers of second monofilament layers are divided into n layers of second welding monofilament layers and h layers of second winding monofilament layers; the n layers of first monofilament layers are welded with the n layers of second welding monofilament layers in one-to-one correspondence; and the h layers of second winding monofilament layers are sequentially wound out of the outermost layer of the n layers of first monofilament layers sequentially from inside to outside in the radial direction. The submarine cable and the manufacturing method therefor provided by the present invention are used for improving the bendability, flexibility and electrical performance of submarine cables.
