Abstract
The invention discloses an acid and alkali resistant cable for coal mine. The acid and alkali resistant cable comprises a cable body, wherein the cable body comprises conductors, a first shielding layer, a second shielding layer and an outer sheath; a plurality of conductors are arranged in the cable body; a polyethylene tube is arranged outside the conductors; the first shielding layer wraps the outside of the polyethylene tube; the second shielding layer is arranged outside the first shielding layer; an anti-corrosion coating tightly extrudes and wraps the outside of the second shielding layer; a waterproof layer extrudes and wraps the outside of the anti-corrosion coating; and the outer sheath tightly extrudes and wraps the outside of the shielding layer. The acid and alkali resistant cable has the advantages of being reasonable in structural design, good in acid and alkali resistance, long in service lifetime and the like.
Description
Technical field
The present invention relates to field of cables, particularly relate to a kind of colliery acid and alkali-resistance cable.
Background technology
At present, along with socioeconomic development, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, such as in aviation, the cable used in the fields such as electric power, high all especially to the requirement of the high pressure resistant and diamagnetic jamming performance aspect of cable, but now used on the market cable is because its structural design is unreasonable or the problem such as material, effective protective effect can not be played, in the use procedure of cable, often certain damage is caused to cable, make cable cover(ing) that damaged situation occur, thus cause cable internal structure to be destroyed, its working state abnormal or inoperable situation is made in the use procedure of cable.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of colliery acid and alkali-resistance cable.
The present invention takes following technical scheme to realize: a kind of colliery acid and alkali-resistance cable, and it comprises cable body, and described cable body comprises conductor, the first screen, secondary shielding layer and oversheath, and described cable body inside is provided with multiple conductor; Layer of polyethylene pipe is set outside described conductor; Described polyethylene pipe outer wrapping one deck first screen; One deck secondary shielding layer is set outside described first screen; Described secondary shielding layer closely extrudes one deck corrosion-resistant coating outward; One deck water blocking layer is extruded outside described corrosion-resistant coating; One deck oversheath is extruded outside described water blocking layer.
Above-mentioned a kind of colliery acid and alkali-resistance cable, described insulating barrier is that cross-linking polyethylene materials is made.
The present invention has following beneficial effect in sum: the present invention has the advantages such as the good and long service life of reasonable in design, acid-proof alkaline, described corrosion-resistant coating ensures that cable body internal structure can not be subject to the corrosion of air and harmful substance, prevent conductor from occurring the situation of variable color, extend the useful life of cable body.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention;
Wherein: 1, cable body; 2, conductor; 3, polyethylene pipe; 4, the first screen; 5, secondary shielding layer; 6, corrosion-resistant coating; 7, water blocking layer; 8, oversheath.
Embodiment
As shown in Figure 1, a kind of colliery acid and alkali-resistance cable, it comprises cable body 1, and described cable body 1 comprises conductor 2, first screen 4, secondary shielding layer 5 and oversheath 8, and described cable body 1 inside is provided with multiple conductor 2; Outside described conductor 2, layer of polyethylene pipe 3 is set; Described polyethylene pipe 3 outer wrapping one deck first screen 4; Outside described first screen 4, one deck secondary shielding layer 5 is set; Described secondary shielding layer 5 is outer closely extrudes one deck corrosion-resistant coating 6; One deck water blocking layer 7 is extruded outside described corrosion-resistant coating 6; One deck oversheath 8 is extruded outside described water blocking layer 7.
Described corrosion-resistant coating 6 ensures that cable body 1 internal structure can not be subject to the corrosion of air and harmful substance, prevents conductor 2 from occurring the situation of variable color, extends the useful life of cable body 1.
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.
