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

Deepwater carrying cable

Technical field

The present invention relates to a kind of load cable.Particularly a kind of ocean or deep quest, the army and the people naval vessel electric equipment of can be used for connects and use electric wire, also can be for the use of connecting up of coastal wetland comprehensive survey control system.

Background technology

The electric equipment that Yu Haiyang or deep quest, the army and the people naval vessel are had a special environment for use connects use line, requires to have the tensile strength height, volume is little, in light weight, soft combination property such as get well.But the conventional electric wire that uses can not satisfy this higher combination property requirement in the prior art.

Summary of the invention

For avoiding above-mentioned existing in prior technology weak point, the purpose of this invention is to provide a kind ofly have composite characteristics such as volume is little, in light weight, load-carrying ability is strong, water resistance is superior, can satisfy in the special environment for use deepwater carrying cable.

The technical solution adopted for the present invention to solve the technical problems is: it comprises core cable and restrictive coating 7, it is by comprising that the conductive core line more than 3 or 3 constitutes the core cable, and be provided with in the central authorities of core cable and block water and tensile core rope 4, and between conductive core line, be filled with and block water and tension rope 5; It is above by 5 above conductive core lines conductive core line layer formed into a circular distribution also to be provided with 1 circle or 2 circles around the core cable; Be disposed with from the inside to the outside in the periphery of conductive core line layer and block water and tensile layer 6 and restrictive coating 7.Described conductive core line comprises conductor 1, insulating barrier 2 and watertight composition 3; Described conductor 1 adopts the silver-plated copper conductor, is enclosed with the insulating barrier 2 that extrudes moulding with fluoroplastics F40 at the skin of described conductor 1; Skin in described insulation 2 is enclosed with the watertight composition 3 that is interwoven with water blocking yarn and aramid yarn.Described blocking water and tension rope 4 and block water and tension rope 5 is interwoven with water blocking yarn and aramid yarn.Described block water and tensile layer 6 be interwoven with water blocking yarn and aramid yarn.Described restrictive coating 7 extrudes moulding with polyamine fat.

The present invention constitutes the conductive core line of core cable and forms any above conductive core line in the conductive core line of conductive core line layer as power line, and other conductive core line is as holding wire.

Compared with the prior art it have following characteristic:

1, the present invention extrudes the profiled insulation layer with fluoroplastics F40, and the insulating barrier wall is thin, volume is little, in light weight and mechanical strength is high, can meet the requirement of airborne equipment and weight well, and provides safe and reliable guarantee for detector or other electric equipments.

2, the present invention does not contain hazardous substance, and belongs to environmentally friendly machine.

3, the present invention mainly is applicable to 250V and following for loss of weight, easy to use, load-carrying ability is strong and security reliability is had relatively high expectations occasion, connect as the installation between electrical system electrical source of power cable and electric equipment, the instrument and meter and to use line, can be widely used in deep-sea, wetland, national defence weapon equipment, all kinds of car and boat onboard system, oil field well logging etc.It both can be used for ocean or deep quest, the army and the people naval vessel electric equipment connects usefulness, also can be for coastal wetland comprehensive survey control system wiring use
