The wire core bundle of the cable comprises a supply lead core, a shielded twisted pair, a power line core, and a rubber filling strip; the supply lead core, the shielded twisted pair, the power line core, and the rubber filling strip are twisted to form the wire core bundle; a water-resisting belt is wrapped outside the wire core bundle; and the water-resisting belt is provided with an inner sheath, an armor layer, and an outer sheath from the inside out. The cable provided by the utility model has enhanced watertightness, one cable can realize various functions, and the cable weight is lightened. The cable is suitable for being used in various ocean engineering.
Description
Technical field
The utility model relates to the electric wire field, relates in particular to a kind of cable that is used for ocean engineering.
Technical background
Along with advancing to ten big fields, 16 great special projects of country and development of high-tech emphasis implement, and manufacturing industry is to the startup of high-end field development strategy, and space flight and aviation, new forms of energy, equipment aspect, ocean and green design, new material aspect are the directions of following tackling key problem.Ocean engineering is the meeting accelerated development in 10 years, gives priority to harbour machinery, marine resources exploration equipment, marine oil and gas development of resources outfit etc., and all kinds of cables also can be to high-tech, high level development.
And at present domestic cable development or the incipient stage that is used for ocean engineering is used for that the umbilical cable of ocean engineering is domestic to have minority producer to do, and what oversheath adopted is thermoplastic elastic material, and the watertightness performance effect of thermoplastic elastic material is not ideal.Simultaneously because of the cable long period of soaking that is used for ocean engineering at seawater, cable suffers the corrosion of seawater and the pressure at deep-sea for a long time, causes cable aging easily, and many usefulness steel wires cause the weight of cable heavier as the materials of armouring in the prior art.In addition, be used for the cable of ocean engineering or electric energy transmitting only in the prior art, a perhaps transmission signals, function is more single.
The utility model content
The purpose of this utility model provides a kind of cable that is used for ocean engineering, and described cable watertightness is effective, and cable weight is lighter, be convenient to install and use, ageing resistace is good, and the current collection line of force, power line, holding wire satisfy a cable and realize multiple function in one.
For achieving the above object, the utility model by the following technical solutions:
A kind of cable that is used for ocean engineering, comprise the core bundle, described core bundle comprises the power supply core, described power supply core periphery lapped shielding layer, screen extrudes pe sheath outward, described core bundle is surrounded with waterstop outward, and described waterstop periphery is provided with inner sheath, armour and oversheath from inside to outside successively.
Described core bundle also comprises Shielded Twisted Pair and power core.
Described Shielded Twisted Pair adopts tinned copper wire flexible conductor polyethylene insulation core right with polyethylene gasket for packing strand, strand to after extrude in the polyethylene and overlap, overlap periphery in the polyethylene and be coated with screen, the screen periphery extrudes the crosslinked polyethylene sheath; Described power core adopts the tinned copper wire flexible conductor to extrude crosslinked polyetylene insulated layer.
Described power supply core, Shielded Twisted Pair and power core strand and core intrafascicularly also twist and packing arranged.
The percentage of braiding coverage of the copper wire woven shield of described Shielded Twisted Pair reaches more than 90%.
Adopt above technical scheme, can reach following technique effect:
(1) because the utility model adopts rubber to make sheath, and between each heart yearn, is provided with waterstop, improved the watertightness of cable, the corrosivity of sea water resistance and the insulating properties of cable like this;
(2) because the utility model adopts nonmetallic aramid fiber rod to substitute steel wire as armoring material, alleviated the weight of cable;
(3) because the utility model current collection line of force, power line, holding wire in one, have improved the practicality of cable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1: the utility model comprises power supply core 1, Shielded Twisted Pair 2, power core 3, inner sheath 4, armour 5 and oversheath 6.It is crosslinked polyetylene insulated that described power supply core 1 adopts the tinned copper wire flexible conductor to extrude, and the wrapped aluminum-plastic composite membrane in the stranded back of insulated wire cores forms screen 7, the screen 7 outer layer of polyethylene sheaths 8 that extrude again.Described Shielded Twisted Pair 2 adopts zinc-plated flexible conductor to extrude polyethylene insulation core 9 and polyethylene gasket for packing 10 strands are right, after extruding in the layer of polyethylene cover 11, the outside of Shielded Twisted Pair 2 carries out the copper wire braid shielded, percentage of braiding coverage reaches more than 90%, and the copper wire braid shielded extrudes layer of polyethylene sheath 12.Described power core 3 adopts the tinned copper wire flexible conductor to extrude crosslinked polyetylene insulated.Also comprise rubber packing 14 in the core of cable, described power supply core 1, Shielded Twisted Pair 2, power core 3 and rubber packing 14 mutually stranded formation core bundles, the wrapped waterstop 13 of core bundle periphery, the utility model adopts two-layer waterstop, extrudes one deck rubber inner sheath 4 in the outside of waterstop 13, adopts aramid fiber to reinforce rod braiding armour 5 then, the outermost layer of cable is an oversheath 6, oversheath 6 adopts the rubber material, and airtight skin makes the watertightness of cable better.
Power supply core 1 of the present utility model adopts 4 cores, and Shielded Twisted Pair 2 adopts 3 pairs, and power heart yearn 3 also adopts 3, and rubber packing 14 adopts 6, can adopt different quantity with different requirements according to different environment when specifically using.
