Embodiment 1

[0012] Embodiment 1, it includes a core cable and a sheath layer 7, the core cable is composed of three or more conductive core wires, and a water-blocking and tensile core rope 4 is arranged in the center of the core cable, and the conductive Water-blocking and tensile ropes 5 are filled between the core wires; a conductive core wire layer consisting of 5 or more conductive core wires distributed in a circle is arranged around the core cable; The outer periphery is provided with a water-blocking and tensile layer 6 and a sheath layer 7 in sequence from the inside to the outside. The water-blocking and tension-resistant rope 4, the water-blocking and tension-resistant rope 5, and the water-blocking and tension-resistant layer 6 can all be interwoven with water-blocking yarn and aramid yarn. treatment can effectively prevent the penetration of water vapor; the aramid yarn has high mechanical strength, especially the tensile strength is superior, and the interweaving of the wate...

Embodiment 2

[0013] Embodiment 2, the conductive core wire of the present invention is composed of three parts: a conductor 1, an insulating layer 2 and a waterproof layer 3, and the conductor 1 is preferably a silver-plated copper conductor, so as to improve the corrosion resistance and mechanical strength of the conductor And improve its welding performance to meet the requirements of vibration occasions; the outer layer of the conductor 1 is an insulating layer 2 that is separately extruded and molded with fluoroplastic F40. The known fluoroplastic F40 is a copolymer of ethylene and tetrafluoroethylene , the specific gravity of the material is light, and it is a thermosetting material. Its application not only improves the reliability of conduction, but also makes the wire flexible, small in size, light in weight, and easy to install and use. The outer layer of the insulating layer 2 is provided with a waterproof layer 3 interwoven with water-blocking yarn and aramid yarn to ensure the w...

Embodiment 3

[0014] Embodiment 3, the present invention can also use part of the conductive core wires in the conductive core wires that constitute the core cable and the conductive core wires that make up the conductive core wire layer as power wires, and the other multiple conductive core wires are used as signal wires. The power line and the signal line are made into one cable, so that the space occupied by the cable can be effectively reduced, and the assembly efficiency can be improved. refer to figure 1 , and the rest are the same as the above-mentioned embodiment.

Abstract

The invention discloses a deepwater carrying cable. The cable mainly solves the technical problems of low tensile strength, large volume, poor flexibility and the like of the conventional common cable. The technical scheme adopts the key points that: more than three conductive core wires form a core cable, the center of the core cable is provided with a water-repellent and tensile core rope, and water-repellent and tensile ropes are filled among the conductive core wires; one or more than two circles of conductive core wire layers composed of more than five conductive core wires in circumferential distribution are arranged around the core cable; and a water-repellent and tensile layer and a sheath layer are sequentially arranged from inside to outside of the periphery of the conductive core wire layer. The cable is mainly suitable for 250 V and below deep-water carrying environment with higher requirements on chemical resistance, fire resistance and safe reliability, serves as a power cable of an electrical system and a wire for installing and connecting electrical equipment and instruments, and can be widely applied to the equipment for deep sea exploration, sea oil logging, national defense weaponry, various vehicle-mounted systems and the like.

Description

technical field [0001] The invention relates to a load cable. In particular, it can be used for marine or deep water exploration, for connecting electrical equipment of military and civilian ships, and can also be used for wiring of coastal wetland comprehensive detection and control systems. Background technique [0002] For marine or deep water exploration, military and civilian ships with special environment for connecting electrical equipment, it is required to have comprehensive properties such as high tensile strength, small size, light weight, and good flexibility. However, the wires and cables routinely used in the prior art cannot meet this relatively high comprehensive performance requirement. Contents of the invention [0003] In order to avoid the deficiencies of the above-mentioned prior art, the purpose of the present invention is to provide a deep-water load cable with comprehensive characteristics such as small size, light weight, strong load capacity, and...
