Abstract
The invention discloses a moisture-proof tensile cable for a coal mine. The moisture-proof tensile cable comprises a cable body; the cable body comprises conductors, an insulation layer, a shielding layer and an outer jacket; the plurality of conductors are arranged in the cable body; a protective layer is arranged outside the conductors; the insulation layer is arranged outside the protective layer; the shielding layer is tightly extruded outside the insulation layer; a waterproof layer is extruded outside the shielding layer; a metal braided layer is tightly extruded outside the waterproof layer; and the outer jacket is extruded outside the metal braided layer. The moisture-proof tensile cable disclosed by the invention has the advantages of being reasonable in structural design, tensile-resistant, corrosion-resistant and the like.
Description
Technical field
The present invention relates to field of cables, particularly relate to the moistureproof stretch-proof cable in a kind of colliery.
Background technology
At present, along with the development of science and technology, the demand of people to cable also gets more and more, cable is a kind of common data-signal transmission equipment, there is message capacity large, the advantages such as the high and security performance of transmission stability is good, but existing cable covering uses some comparatively general polymer, not only useful life is short, and the situation of contaminated environment can be there is, and partial cables because of its structural design unreasonable, use in the environment that moisture is larger, steam is easy to invade cable inside, cause cable internal short-circuit, make signal that the situations such as leakage occur, very large loss is brought to enterprise.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide the moistureproof stretch-proof cable in a kind of colliery.
The present invention takes following technical scheme to realize: the moistureproof stretch-proof cable in a kind of colliery, and it comprises cable body, and described cable body comprises conductor, insulating barrier, screen and oversheath, and described cable body inside is provided with multiple conductor; Outside described conductor, layer protective layer is set; One deck insulating barrier is set outside described protective layer; Described insulating barrier closely extrudes one deck screen outward; One deck water blocking layer is extruded outside described screen; Described water blocking layer closely extrudes layer of metal braid outward; One deck oversheath is extruded outside described wire sheathing.
The moistureproof stretch-proof cable in above-mentioned a kind of colliery, between described protective layer and insulating barrier, gap portion is provided with packed layer.
The moistureproof stretch-proof cable in above-mentioned a kind of colliery, described wire sheathing is that stainless steel wire braiding forms, and is network structure.
The present invention has following beneficial effect in sum: the present invention has reasonable in design, stretch-proof and the advantage such as anticorrosive, described wire sheathing is that stainless steel wire braiding forms, there is the advantages such as the high and transmission attenuation of transmission frequency is little, the transfer of data of communication apparatus can be widely used in.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention;
Wherein: 1, cable body; 2, conductor; 3, protective layer; 4, packed layer; 5, insulating barrier; 6, screen; 7, water blocking layer; 8, wire sheathing; 9, oversheath.
Embodiment
As shown in Figure 1, the moistureproof stretch-proof cable in a kind of colliery, it comprises cable body 1, and described cable body 1 comprises conductor 2, insulating barrier 5, screen 6 and oversheath 9, and described cable body 1 inside is provided with multiple conductor 2; Outside described conductor 2, layer protective layer 3 is set; Outside described protective layer 3, one deck insulating barrier 5 is set; Described insulating barrier 5 is outer closely extrudes one deck screen 6; One deck water blocking layer 7 is extruded outside described screen 6; Described water blocking layer 7 is outer closely extrudes layer of metal braid 8; One deck oversheath 9 is extruded outside described wire sheathing 8.
Described wire sheathing 8 forms for stainless steel wire braiding, has the advantages such as the high and transmission attenuation of transmission frequency is little, can be widely used in the transfer of data of communication apparatus.
The above is embodiments of the invention, therefore all equivalences done according to structure, feature and the principle described in the present patent application scope change or modify, and are included in patent claim of the present invention.
