Suspension type seabed carbon fiber compound cable

Abstract

The invention discloses a suspension type seabed carbon fiber compound cable which comprises a carbon fiber cable core, an optical fiber bundle and a protecting sleeve. The carbon fiber cable core comprises a conductive copper rod, a carbon fiber twisting bundle is twisted on the conductive copper rod, an insulation shielding layer is arranged outside the carbon fiber twisting bundle, a silicon crystal waterproof layer is arranged outside the insulation shielding layer. The optical fiber bundle comprises a metallic framework, a plurality of optical fiber wires are arranged in the metallic framework, and a carbon fiber adhesive layer is arranged outside the metallic framework. The tensile strength of the suspension type seabed carbon fiber compound cable is improved by 30-40% in comparison with the tensile strength of a steel wire, the suspension type seabed carbon fiber compound cable has high-strength cable tractive capability, not only can the weight of the cable be borne, but also the cable can be suspended in the sea according to the requirements of the cable construction site, the submergence depth of the cable can reach 20-200m, the cable can guarantee that a traffic ship runs freely on the water surface, the bearing capacity of the cable can overcome stress fluctuation influence generated by tidal sand and surge in the sea, and the suspension type seabed carbon fiber compound cable is good in waterproof performance and suitable for long-term underwater working environment.

Description

technical field [0001] The invention relates to a carbon fiber cable, in particular to a suspended submarine carbon fiber composite cable. Background technique [0002] Submarine cables are mainly used for information transmission and power transmission between islands or offshore facilities. With the development of offshore wind power and the construction of offshore oil drilling platforms, there are more and more offshore facilities, forming a network of offshore facilities. The distance is as far as 3-5km, and the short distance is between a few hundred meters. It is inappropriate to use the traditional submarine cable connection method to transmit power and communication. Traditional submarine cables use circular steel wires twisted as armor protection layer. This steel wire armor layer can effectively increase the traction mechanical properties of the cable, but a large part of it is consumed by the cable's own weight, which affects the life of the cable. With the rapi...
