Abstract (en)
[origin: EP4199007A1] The invention provides a submarine cable and a method for manufacturing the same, relates to the field of cable technologies and is directed to solve the technical problem of poor bendability, flexibility and electrical performance of the submarine cable. The submarine cable includes a submarine cable section and a landing cable section, where the submarine cable section includes a first conductor, the first conductor includes n first monofilament layers, the landing cable section includes a second conductor, and the second conductor includes m second monofilament layers, the m second monofilament layers are divided into n second welding monofilament layers and h second winding monofilament layers; the n first monofilament layers are welded to the n second welding monofilament layers in a one-to-one relationship; and the h second winding monofilament layers are, sequentially from inside to outside in the radial direction of the submarine cable, wound outside an outermost layer of the n first monofilament layers. The submarine cable and the method for manufacturing the same provided by the invention are directed to improve the bendability, flexibility and electrical performance of the submarine cable.
