Document Type and Number:
WIPO Patent Application WO/2021/164230
Kind Code:
A1
Abstract:
A non-metallic armored submarine cable. The submarine cable comprises a central cable consisting of one or more electric units, armor layers, and an outer coating layer; the armor layers are twisted on the outside of the central cable; the outer coating layer is sleeved on the outside of the armor layers; each armor layer is formed by stranding a plurality of circular or flat non-metallic armored elements and/or a plurality of armored metal wires; when the non-metallic armored element is circular, the non-metallic armored element consists of a non-metallic rod and an outer sheath extruded and coated on the outside of the non-metallic rod, or is composed of a central rod body composed of a plurality of stacked non-metallic rods, and an outer sheath extruded and coated on the outside of the central rod body; and when the non-metallic armored element is flat, the non-metallic armored element is composed of a plurality of non-metallic rods and an outer sheath extruded and coated on the outside. According to the present invention, the problems of large submarine cable weight and large force of vertical laying and mounting under the condition of large water depth are solved, a lighter submarine cable weight is achieved while the mechanical performance of deep submarine cables is ensured, and the safety of laying construction and operation of submarine cables is facilitated to be ensured.
