Abstract

The utility model discloses a mining waterproof rubber-jacketed flexible cable which comprises a cable core. Three power wire cores and a monitoring wire core are stranded to form the cable core, an inner jacket is extruded on the outside of the cable core, and an outer jacket is extruded on the outermost layer of the cable; a reinforcing layer is further arranged between the inner jacket and the outer jacket; each power wire core comprises a power conductor, a power wire core insulating layer and a shielding layer, each power wire core insulating layer is extruded on the outside of the corresponding power conductor, and each shielding layer is braided on the outside of the corresponding power wire core insulating layer; and the monitoring wire core comprises a monitoring conductor and a monitoring wire core insulating layer which is extruded on the outside of the monitoring conductor. The mining waterproof rubber-jacketed flexible cable has the advantages that the mining waterproof rubber-jacketed flexible cable is excellent in moisture-proof, corrosion-resistant and waterproof performance, can be installed and laid conveniently, and is suitable for mines, tunnels and the like under severe environmental conditions and places in high-humidity and high-corrosion environments, and the flexibility of the cable is unaffected.

Description

A kind of mining rubber sleeve flexible cable that blocks water

Technical field

The utility model relates to the electric wire field, specifically refers to a kind of mining rubber sleeve flexible cable that blocks water.

Background technology

The mining Plastic-sheathed Cable that blocks water is generally in the mine, environmental conditions such as tunnel are abominable, has high humility, the highly corrosive environments occasion is used, cable might be immersed in the water (steam) for a long time, even by a large amount of corrosive gas encirclements, this environment is to the protection against the tide of cable, anticorrosion, block-water performance requires high, and the general structure of the existing mining Plastic-sheathed Cable that blocks water is comparatively single, there is not emphasis to pay attention to the cable block-water performance, moistureproof, the structural design of Corrosion Protection, and, existing cable improves in performance, structural design, even comprise on last self the flexibility of cable and can't reach optimal design.

The utility model content

Technical problem to be solved in the utility model provides a kind ofly has fabulous protection against the tide, anticorrosion, block-water performance, and does not influence cable self flexibility, the convenient new type mining that the lays rubber sleeve flexible cable that blocks water of installing.

A kind of mining rubber sleeve flexible cable that blocks water described in the utility model comprises cable core, and described cable core monitors by three power cores and one that core is stranded and form that cable core extrudes inner sheath outward, and the cable outermost layer extrudes oversheath; Between inner sheath and oversheath, also be provided with reinforced layer; Described power core by the power conductor, be extruded in the outer power line core insulation layer of power conductor and be woven in the outer screen of power line core insulation layer and constitute; Described supervision core monitors that by monitoring conductor and being extruded in the outer pilot wire core insulation layer of conductor constitutes.

Further improve, described three power cores are provided with packed layer with monitoring core center gap place when stranded stranding.

Further improve, described reinforced layer is formed by aramid yarn and water blocking yarn braiding; Described oversheath is the neoprene sheath.

Further improve, it is stranded the forming of tin-coated copper lead of 0.29mm or 0.39mm that described power conductor, supervision conductor adopt filament diameter.

Further improve, described power line core insulation layer, pilot wire core insulation layer adopt the Ethylene Propylene Terpolymer insulating cement again.

The beneficial effects of the utility model:

1, reinforced layer of the present utility model places between sheath and the outer jacket, many aramid yarns intersections are woven in the surface of cable sheath uniformly, outer jacket is closely extruded outside reinforced layer, thereby reinforced layer and inside and outside sheath are fitted tightly, can guarantee that cable has tear resistance and the anti-performance that pulls preferably in use, simultaneously, having avoided cable cover(ing) to play bulging situation preferably occurs.

2, high strength, Ethylene Propylene Terpolymer insulating cement that insulation property are good are adopted in insulation of the present utility model, its tensile strength reaches 14.0Mpa, be 3 times of common Ethylene Propylene Terpolymer tensile strength, and through research repeatedly, make the electric pressure of second third Insulation Material bring up to 35kV from 10kV, tensile strength and tear strength are provided.

3, oversheath of the present utility model adopts high strength, high anti-tear, wear-resisting neoprene sheath, its tensile strength reaches 16MPa, is 2 times of common rubber sheath, and has resistance to low temperature preferably, can guarantee cable in use, sheath can be good at protecting cable core to avoid damage; Simultaneously, can guarantee cable normally operation in-40 ℃ low temperature environment.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Embodiment

As shown in Figure 1, a kind of mining rubber sleeve flexible cable that blocks water described in the utility model comprises cable core, and described cable core monitors by three power cores and one that core is stranded and forms, cable core extrudes inner sheath 7 outward, and the cable outermost layer extrudes the oversheath 9 that adopts neoprene; Between inner sheath and oversheath, also be provided with reinforced layer 8; Described power core is provided with packed layer 4 with monitoring core center gap place when stranded stranding.

Power core described above by power conductor 1, be extruded in the outer power line core insulation layer 2 of power conductor 1 and be woven in power line core insulation layer 2 outer screen 3 and constitute; Described supervision core monitors that by monitoring conductor 5 and being extruded in conductor 5 outer pilot wire core insulation layers 6 constitute.

It is stranded the forming of tin-coated copper lead of 0.29mm or 0.39mm that power conductor 1 described above, supervision conductor 5 adopt filament diameters; Described power line core insulation layer, pilot wire core insulation layer adopt the Ethylene Propylene Terpolymer insulating cement.

The utility model provides a kind of thinking and implementation method of the mining rubber sleeve flexible cable that blocks water; concrete application approach is a lot; the above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvement, these improvement also should be considered as protection range of the present utility model.
