Abstract
Disclosed in the utility model is an intrinsic safety explosion-proof type power cable. The power cable comprises a cable core; a filling layer is arranged at the gap of the cable core; a wrapping layer coats the outside of the cable core; and the outside of the wrapping layer are successively extruded by an inner sheath, a braiding layer, and an outer sheath from inside to outside. The cable core is formed by twisting of three insulated wire cores; and the insulated wire cores include conductors, fire-proof layers, insulated layers, and water blocking layers, wherein the fire-proof layers, the insulated layers, and the water blocking layers are successively arranged outside the conductors by an extruding way. On the basis of the cable structure design and the material selection, the cable has fireproof, water-blocking, high temperature-proof, and external signal shielding characteristics; the security performance is high; and the service life of the cable is long. The cable can be widely applied to occasions requiring high explosion-proof performances, wherein the occasions include a high-rise building, a power plant, chemical engineering, a mine and a subway.
Description
Technical field
The utility model relates to the electric wire field, specifically refers to a kind of intrinsic safe explosion-proof type power cable.
Background technology
At present, power cable is as the main carriers of China's electric energy transmitting, for remarkable contribution has been made in development and the progress of Chinese society.Along with industrial expansion, the range of application of power cable is originally more extensive, common power cable is often due to the performance limitations of use material or the defect of Cable Construction Design, cause that cable fire is poor, water preventing ability is poor, heat-resisting quantity is poor, also be subject to the interference of outer signals, thereby cause the frequent generation of cable fault, cause casualties and economic loss.
The utility model content
Technical problem to be solved in the utility model be to provide a kind of fire-resistant, block water, high temperature resistant and the shielding outer signals, security performance is higher, the intrinsic safe explosion-proof type power cable of long service life.
A kind of intrinsic safe explosion-proof type power cable described in the utility model, comprise cable core, in the cable core gap, is provided with packed layer, cable core outer cladding lapping layer, extrudes from inside to outside successively inner sheath, braid, oversheath outside lapping layer; Described cable core is to thoroughly do away with stranded the forming of edge core by three, and its insulated wire cores is by conductor and is extruded in successively conductor outer flame retardant coating, insulating barrier, waterstop and forms.
Further improve the described lapping layer lap wound glass fibre belt structure of double-baging of attaching most importance to.
Further improve, described braid is tinned copper wire braiding sheathed structure again.
The beneficial effects of the utility model are:
This anti-explosion cable adopts the wrapped fire-resistant isinglass belt of conductor, insulation and sheath to adopt high-temperature-resisting silicon rubber material, the wrapped waterstop in insulated wire cores outside, the cable core outside extrudes in silicon rubber to be protected, in protect outside and adopt the tinned copper wire braiding, the braid outside extrudes one deck silicon rubber oversheath, because silicon rubber has high temperature resistant and low temperature resistant duality, so that the setting of this novel cable structure has is high temperature resistant, block water, shield the multi-functional that outer signals is disturbed.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of intrinsic safe explosion-proof type power cable described in the utility model, comprise cable core, in the cable core gap, is provided with packed layer 5, cable core outer cladding lapping layer 6, extrudes from inside to outside successively inner sheath 7, braid 8, oversheath 9 outside lapping layer 6; Described cable core is to thoroughly do away with stranded the forming of edge core by three, and its insulated wire cores is by conductor 1 and is extruded in successively conductor 1 outer flame retardant coating 2, insulating barrier 3, waterstop 4 and forms.
The lapping layer 6 described above lap wound glass fibre belt structure of double-baging of attaching most importance to; Braid 8 is tinned copper wire braiding sheathed structure.
The concrete application approach of the utility model is a lot; the above is only 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.
