Description
Technical field
The utility model relates to field of cables, particularly relates to the anti-interference power cable of a kind of industrial stretch-proof.
Background technology
At present, along with the development of science and technology, the fields such as industry are also at rapid advances, what bring is the increase of cable consumption thereupon, cable normally has several or several groups of wires often to organize the cable of at least two stranded similar ropes, often organize mutually insulated between wire, and be often twisted into around a center, whole outside is surrounded by the cover layer of high-insulation, the kind of cable has a lot, the environment for use that can be applied in fields different in a lot of field is different, therefore different requirements is also had to cable, but existing cable because of its structural design unreasonable, the area that some environment are comparatively severe can not be adapted to, often there is the situation that sheath ruptures after a long time use, cause cable internal structure damaged, very large trouble is brought to the work in later stage.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide the anti-interference power cable of a kind of industrial stretch-proof.
The utility model is taked following technical scheme to realize: the anti-interference power cable of a kind of industrial stretch-proof, and it comprises cable body, and described cable body comprises conductor, insulating barrier, screen and oversheath, and described cable body inside is provided with many conductors; Described conductor is outside equipped with protective layer; Jointly cable core is formed between described protective layer and conductor; Described cable body inside is provided with many cable cores; Described cable core closely extrudes a layer insulating outward; Between described insulating barrier and cable core, gap portion is provided with packed layer; Described insulating barrier closely extrudes one deck screen outward; Described screen is extruded with anticorrosive coat, plastic-aluminum combined belt and metal armor layers from inside to outside successively; Described metal armor layers closely extrudes one deck oversheath outward.
The above-mentioned anti-interference power cable of one industry stretch-proof, described conductor adopts real core copper core or multiply to press copper core and makes, and its cross sectional shape is circular or sector structure.
The above-mentioned anti-interference power cable of one industry stretch-proof, described anticorrosive coat is carbon fiber tape or ceramic fibre strip.
The above-mentioned anti-interference power cable of one industry stretch-proof, the packed layer arranged between described insulating barrier and cable core is glass cord.
The anti-interference power cable of above-mentioned one industry stretch-proof, described insulating barrier, Thickness Ratio between screen and anticorrosive coat are 1:1:1.
The above-mentioned anti-interference power cable of one industry stretch-proof, described oversheath is butyronitrile polyvinyl chloride elastomeric material.
The utility model has following beneficial effect in sum: this cable has good shielding properties, the advantage such as anti-interference and high temperature resistant; described metal armor layers ensure that cable completely can the effect of load-bearing own wt and external tensile force when high-drop installation; cable is played a very good protection, there is excellent stretch-proof performance.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional structure schematic diagram;
Wherein: 1, cable body; 2, conductor; 3, protective layer; 4, packed layer; 5, insulating barrier; 6, screen; 7, anticorrosive coat; 8, plastic-aluminum combined belt; 9, metal armor layers; 10, oversheath.
Embodiment
As shown in Figure 1, the anti-interference power cable of a kind of industrial stretch-proof, it comprises cable body 1, and described cable body 1 comprises conductor 2, insulating barrier 5, screen 6 and oversheath 10, and described cable body 1 inside is provided with many conductors 2; Described conductor 2 is outside equipped with protective layer 3; Jointly cable core is formed between described protective layer 3 and conductor 2; Described cable body 1 inside is provided with many cable cores; Described cable core closely extrudes a layer insulating 5 outward; Between described insulating barrier 5 and cable core, gap portion is provided with packed layer 4; Described insulating barrier 5 is outer closely extrudes one deck screen 6; Described screen 6 is extruded with anticorrosive coat 7, plastic-aluminum combined belt 8 and metal armor layers 9 from inside to outside successively; Described metal armor layers 9 is outer closely extrudes one deck oversheath 10.
Described conductor 2 adopts real core copper core or multiply to press copper core and makes, its cross sectional shape is circular or sector structure, not only substantially increase the operating efficiency of cable, also make its work more stable, and described conductor 2 structure is easy to processing, making length is unrestricted, has certain flexibility and bendability during use, facilitates the laying of workpeople; The outer protective layer 3 arranged of described conductor 2 effectively can improve the stretch-proof performance of conductor 2, also can not rupture easily, greatly extend the useful life of conductor 2 even if be subject to larger pressure; The packed layer 4 that gap portion between described insulating barrier 5 and cable core is arranged is glass cord, cable can not only be kept can not to produce deformation because being subject to external force, and externally can pass to heat, the transmittability of cable is increased greatly, improves the operating efficiency of cable; Described insulating barrier 5 can improve the insulation property of cable body 1, makes its work more stable; The screen 6 extruded outside described insulating barrier 5 makes cable body 1 effectively can prevent signal disturbing, makes in its signals transmission more stable; The outer anticorrosive coat 7 arranged of described screen 6 ensures that conductor 2 can not be subject to the corrosion of harmful substance, prevents the variable color of conductor 2, extends the useful life of cable; Described plastic-aluminum combined belt 8 improves the structural strength of cable body 1 inside, can stretch-proof; Described metal armor layers 9 ensure that cable completely can the effect of load-bearing own wt and external tensile force when high-drop installation, plays a very good protection, have excellent stretch-proof performance to cable; Described oversheath 10 makes cable have resistant to elevated temperatures effect for butyronitrile polyvinyl chloride elastomeric material, normally can work for a long time, substantially increase the useful life of cable under the adverse circumstances such as HTHP.
The above is the utility model embodiment, therefore all equivalences done according to structure, feature and the principle described in the utility model application range change or modify, and are included in the utility model patent claim.
