Description

A kind of wire armoring composite tow

Technical field

The utility model relates to a kind of cable, and particularly a kind of wire armoring composite tow, belongs to field of cable technology.

Background technology

Cable is normally by the cable of several or the stranded similar rope of several groups of wires (often organizing at least two), and often organize mutually insulated between wire, and be often twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.Cable has interior energising, the feature of external insulation.Cable has power cable, control cables, compensating cable, shielded type cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resisting cable, shipboard cable, mining cable, aluminium alloy cable etc.They are all made up of sub-thread or stranded conductor and insulating barrier, are used for connecting circuit, electrical equipment.

But because cable place used is different, the composition of cable is also different, and the cable in such as seawater just must have high strength, low-density and loose thermal property.

Therefore, need to design a kind of wire armoring composite tow be applicable in seawater.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of wire armoring composite tow, effectively can solve the problem in background technology.

In order to solve the problems of the technologies described above, the utility model provides following technical scheme:

The utility model relates to a kind of wire armoring composite tow, comprises steel wire rope, and the peripheral coated one deck liner of described steel wire rope, is arranged with 2 core loose tube fibers and 4 core 1.5m outside described liner ²power line, described 2 core loose tube fibers and 4 core 1.5m ²physical blowing polyethylene is filled with, described 2 core loose tube fibers and 4 core 1.5m between power line ²the peripheral coated one deck sheath of power line.

As a kind of optimal technical scheme of the present utility model, described steel wire rope is the zinc-plated bright wire rope of high strength, and described wirerope diameter is 9mm, and intensity is greater than 170kgf/mm^2.

As a kind of optimal technical scheme of the present utility model, described liner is physical blowing polyethylene liner, and described liner uses the arrangement of multiple 4 ~ 5mm physical blowing cylinder to be formed, foam degrees 80%.

As a kind of optimal technical scheme of the present utility model, described 4 core 1.5m ²power line is five groups, and often organizes described 4 core 1.5m ²power line uses tinned wird stranded conductor polytetrafluoroethylene as insulation, described 4 core 1.5m ²power line skin is wrapped by band.

As a kind of optimal technical scheme of the present utility model, described 2 core loose tube fibers are 4 four groups.

As a kind of optimal technical scheme of the present utility model, described sheath is sea water resistance rubber-plastic elastomer sheath.

The beneficial effect that the utility model reaches is: can depth capacity 200 meters use in seabed, and has the performance of insulation, low-density and heat radiation, can carry the operating pressure of four tons.

Accompanying drawing explanation

Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for specification, is used from explanation the utility model, does not form restriction of the present utility model with embodiment one of the present utility model.

In the accompanying drawings:

Fig. 1 is the structural representation of a kind of wire armoring composite tow described in the utility model embodiment;

Number in the figure: 1, steel wire rope; 2, liner; 3,2 core loose tube fibers; 4,4 core 1.5m ²power line; 5, sheath.

Embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.

Embodiment: as shown in Figure 1, a kind of wire armoring composite tow of the utility model, comprises steel wire rope 1, the peripheral coated one deck liner 2 of described steel wire rope 1, is arranged with 2 core loose tube fiber 3 and 4 core 1.5m outside described liner 2 ²power line 4, described 2 core loose tube fiber 3 and 4 core 1.5m ²physical blowing polyethylene is filled with, described 2 core loose tube fiber 3 and 4 core 1.5m between power line 4 ²the peripheral coated one deck sheath 5 of power line 4.

Steel wire rope 1 is the zinc-plated bright wire rope 1 of high strength, and steel wire rope 1 diameter is 9mm, and intensity is greater than 170kgf/mm^2, can meet the working pulling force of 4 tons.

Liner 2 is physical blowing polyethylene liner 2, and liner 2 uses multiple 4 ~ 5mm physical blowing cylinder to arrange and formed, foam degrees 80%, and sheath 5 is sea water resistance rubber-plastic elastomer sheath 5, reduces global density, balance proportion.

4 core 1.5m ²power line 4 is five groups, and often group makes 4 core 1.5m ²power line 4 as insulation, can guarantee current-carrying capacity of cable with tinned wird stranded conductor polytetrafluoroethylene; 4 core 1.5m ²power line 4 skin is wrapped by band, and often group improves by band is wrapped the thermal capacity often organized, and fiber unit is organized abundant the isolation with other and ensured that heat fully distributes.

The utility model can depth capacity 200 meters use in seabed, and has the performance of insulation, low-density and heat radiation, can carry the operating pressure of four tons.

Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
