WIPO Patent Application WO/2021/208304
Kind Code:
A1
Abstract:
A submarine cable and a preparation method therefor. The submarine cable comprises a plurality of structural units and a protection unit, wherein the protection unit is arranged on the periphery of the structural units; the protection unit comprises an outer protection layer and armor layers, which are arranged on the periphery; the armor layers are located between the outer protection layer and the structural units; two armor layers are provided; and an included angle between a monofilament of the inner armor layer and the axis of the submarine cable is greater than an included angle between a monofilament of the outer armor layer and the axis of the submarine cable, or the directions of included angles between monofilaments of the two armor layers and the axis of the submarine cable are opposite one another. According to the submarine cable, by means of limitations on angles between monofilaments of two armor layers and a central horizontal line, gaps between the monofilaments of the two armor layers have different angles or directions in the axial direction, thereby providing stronger protection for the submarine cable.
