A photoelectric composite cable used for tidal power generation

Abstract

A photoelectric composite cable used for tidal power generation is disclosed. The composite cable includes a control line core, a plurality of power line core conductors and at least one optical unit. The control line core is formed by twisting three control copper conductors the centers of which having reinforced bars. The control copper conductors are covered with a first insulating layer. The plurality of power line core conductors and the at least one optical unit are covered with a sub-internal sheath layer. The sub-internal sheath layer is covered with an armoured anticorrosion layer. The armoured anticorrosion layer is covered with an external sheath layer. The external sheath layer includes, by weight, crude chloroprene rubber 320F, tetramethylthiuram disulfide, 2-mercaptobenzothiazole, 2-mercaptobenzimidazole, N,N'-bis(2-naphthyl)-p-phenylenediamine, stearic acid, paraffin, zinc oxide, gas-mixed carbon black, talcum powder, calcium carbonate, and dioctyl sebacate. The composite cable has characteristics of excellent resistance to ultraviolet light, resistance to low temperature, tear resistance, ageing resistance, corrosion resistance and oil resistance.

Description

technical field [0001] The invention relates to the technical field of photoelectric composite cables, in particular to a photoelectric composite cable for tidal power generation. Background technique [0002] The photoelectric composite cable for tidal power generation is used in tidal seawater near the coast or islands, mainly for the connection of the ocean shore to the tidal generator and the connection of the fixed anchor pile on the seabed to the tidal generator suspended in seawater; the existing The product has the following technical problems: [0003] (1) The product is laid outdoors and is often used in harsh marine environmental conditions, such as: long-term sun exposure to ultraviolet rays, seawater immersion, sediment erosion and other coastal natural conditions, the performance declines relatively quickly and the service life is relatively short; [0004] (2) During the use of the cable, the cable must withstand tensile force, torsion and bending fatigue, re...
