Abstract
The utility model discloses a high-strength communication cable for a coal mine, which comprises an insulation cable core. An inner insulation protective sleeve is wrapped outside the cable core; an outer protective sleeve is wrapped outside the inner insulation protective sleeve; at least one reinforcing rib arranged longitudinally is arranged between the inner insulation protective sleeve and the outer protective sleeve; an armored shielding layer is arranged between the inner insulation protective sleeve and the outer protective sleeve; and a core body of the cable core is made by mixing and twisting a steel wire and a copper wire. The high-strength communication cable for the coal mine is capable of not only bearing frequent pulling and bending, prolonging the service life of the communication cable, but also increasing anti-interference and anti-corrosion capabilities of communication cable transmission signals. Besides, the communication cable can be directly laid inside a level and a sloping lane which have high mechanical damage ratio inside the coal mine.
Description
Technical field
The utility model relates to a kind of telecommunication cable, particularly a kind of telecommunication cable that is used for the higher location of mechanical damage intensity in the colliery.
Background technology
The telecommunication cable that in colliery gallery and inclined gallery, is provided with, by more frequent laying, pulling and bending, mechanical damage intensity is higher, and this just needs to use to have stronger tensile strength at these local telecommunication cables.At present, the telecommunication cable that uses in the colliery, its structure is generally: comprise the copper cash core at the center of being arranged on, coat polyethylene layer outside the copper cash core, coat the polyvinyl chloride insulation sheath outside polyethylene layer.The cable of this structure, though transmission performance and insulation property are better, the tension dynamics is not enough, and useful life is short, and signal is subject to external magnetic field and disturbs, and the antijamming capability of transmission signals is poor.Along with the develop rapidly of domestic and international information industry, in communication control system, particularly communication control system is had higher requirement to telecommunication cable under the coal mine.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of colliery high-strength telecommunication cable, to improve the tensile strength of telecommunication cable, prolong the useful life of telecommunication cable.
For solving the problems of the technologies described above, the technical solution of the utility model is: the high-strength telecommunication cable in colliery, comprise the insulation cable core, be coated with the insulation inner sheath at described cable core, outside described insulation inner sheath, coat oversheath, between described insulation inner sheath and described oversheath, be provided with at least one reinforcement of vertical arrangement.
As a kind of optimized technical scheme, described reinforcement is a steel wire.
As a kind of optimized technical scheme, described reinforcement is provided with 4, and described reinforcement evenly distributes for 90 ° at circumferencial direction.
As a kind of optimized technical scheme, between described insulation inner sheath and described oversheath, be provided with the armouring screen.
As a kind of optimized technical scheme, the core body of described cable core mixes strand by steel wire and copper cash and makes.
After having adopted technique scheme, the beneficial effects of the utility model are: the high-strength telecommunication cable in colliery of the present utility model, between insulation inner sheath and oversheath, be provided with at least one reinforcement of vertical arrangement, reinforcement the endwise tensile strength that has strengthened telecommunication cable is set, make telecommunication cable can tolerate frequent pulling and bending, prolonged the useful life of telecommunication cable.Between insulation inner sheath and oversheath, be provided with the armouring screen, not only improved the antijamming capability of telecommunication cable transmission signals, and strengthened the mechanical strength of telecommunication cable, improved the anti-erosiveness of telecommunication cable, in the colliery, in the higher gallery and inclined gallery of mechanical damage, can directly lay.In addition, the core body of the cable core that this use is novel mixes strand by steel wire and copper cash and makes, and has further improved the mechanical tensile strength of telecommunication cable.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure: 1. cable core, 11. core bodys, 2. insulation inner sheath, 3. armouring screen, 4. reinforcement, 5. oversheath.
Embodiment
As shown in drawings, the high-strength telecommunication cable in a kind of colliery.It comprises the insulation cable core 1 that is arranged at the center, and in the present embodiment, insulation cable core 1 is by two pairs of stranded forming of twisted-pair feeder, and certainly, insulation cable core 1 also can be combined by the core of alternate manner, quantity.Core body 11 in the insulation cable core 1 is to mix strand by steel wire and copper cash to make, because the mechanical strength of steel wire than higher, has therefore improved the mechanical tensile strength of telecommunication cable.
Be coated with insulation inner sheath 2 in the periphery of insulation cable core 1, be made by polythene material, insulation property are relatively good.Periphery at insulation inner sheath 2 coats an armouring screen 3, preferred wire armoring shielding, not only improved the antijamming capability of telecommunication cable transmission signals, and strengthened the mechanical strength of telecommunication cable, improved the anti-erosiveness of telecommunication cable, in the colliery, in the higher gallery and inclined gallery of mechanical damage, can directly lay.
Extrude the oversheath 5 that pvc material is made in the periphery of armouring screen 3, between armouring screen 3 and oversheath 5, be provided with at least one reinforcement 4 of vertical arrangement, the reinforcement 4 preferred steel wires that use, in the present embodiment, used 4 reinforcements 4, they are 90 ° of evenly distributions along the circumferential direction.Reinforcement 4 the endwise tensile strength that has strengthened telecommunication cable is set, make telecommunication cable can tolerate frequent pulling and bending, prolonged the useful life of telecommunication cable.
The foregoing description only is giving an example of the utility model embodiment; protection range of the present utility model is as the criterion with the content of claim; any equivalent transformation that carries out based on technology enlightenment of the present utility model is also within protection range of the present utility model.
Claims (5)
1. the high-strength telecommunication cable in colliery, comprise the insulation cable core, be coated with the insulation inner sheath at described cable core, outside described insulation inner sheath, coat oversheath, it is characterized in that: at least one reinforcement that between described insulation inner sheath and described oversheath, is provided with vertical arrangement.
