Abstract

The invention discloses a special seabed power cable for the ocean. The special seabed power cable for the ocean comprises a cable core containing five conducting wire pairs, wherein one conducting wire pair and the cable core are arranged coaxially, the other four conducting wire pairs are longitudinally distributed around the conducting wire pair located in the center in parallel, and space among the conducting wire pairs is filled with flexible material, so that the cable core is rounded; a waterproof wrapping tape is wrapped on the periphery of the cable core to form a first waterproof layer, a netted tear-resistant rope is wound on the periphery of the first waterproof layer to form a first tear-resistant layer, a steel wire armored layer is arranged on the periphery of the first tear-resistant layer, two sides of the steel wire armored layer are coated with pitch respectively to form a first pitch layer and a second pitch layer, a netted tear-resistant rope is wound on the periphery of the second pitch layer to form a second tear-resistant layer, a waterproof wrapping tape is wound on the periphery of the second tear-resistant layer to form a second waterproof layer, and a protecting cover is wrapped on the periphery of the second waterproof layer in an extruded mode. The special seabed power cable for the ocean is compact in structure, excellent in waterproof performance, and high in tensile strength.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a submarine power cable dedicated for ocean use. Background technique [0002] Submarine cables are laid on the seabed and are used for the development and utilization of marine energy and other power supply systems for power transmission. In recent years, with the development of my country's marine economic construction, the development of coastal islands and marine energy has accelerated, and the demand for submarine cables has increased rapidly. Between islands, between islands and cities, offshore oil platforms, deep-sea energy development, and offshore wind power generation etc. all need large quantities of submarine cables. Existing submarine cables cannot meet the requirements of the submarine environment in terms of waterproofing and tensile strength. Contents of the invention [0003] In order to solve the technical problems in the background technology, the present in...
