Description
Technical field
The utility model relates to field of cables, particularly relates to a kind of power cable with cross-linked polyethylene insulation.
Background technology
At present, along with the development of science and technology, the consumption of electric wire is also increasing considerably, cable used on the market generally includes conductor, insulating barrier, screen and oversheath formation now, the structure of this cable is comparatively simple, under some rugged environments, cable just can not well normally work, and in long-time use, easily there is situation about rupturing in cable, and existing cross-linking polyethylene materials not only has excellent electrical insulation properties, and useful life is longer, so this kind of material is widely used.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of power cable with cross-linked polyethylene insulation.
The utility model is taked following technical scheme to realize: a kind of power cable with cross-linked polyethylene insulation, 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; Described cable body cross section is circular configuration; Described conductor outer wrapping one deck protective sleeve; Described protective sleeve and conductor form cable core jointly; One deck insulating barrier is set outside described cable core; Between described cable core and insulating barrier, gap portion is provided with multiple elasticity packing; The gap portion that described cable core, insulating barrier and elasticity packing are formed is provided with packed layer; Described insulating barrier closely extrudes one deck screen outward; Described screen is extruded with heat-insulation layer from inside to outside successively, block water twining package tape and inner sheath; Described inner sheath closely extrudes one deck oversheath outward.
Above-mentioned a kind of cross-inked polyethylene power cable, described conductor is strandedly press circular copper conductors structure, and described cross-sectional area of conductor is circular or sector structure.
Above-mentioned a kind of cross-inked polyethylene power cable, described packed layer is glass cord or polypropylene fiber rope.
Above-mentioned a kind of cross-inked polyethylene power cable, described heat-insulation layer is that asbestos fibre material is made.
Above-mentioned a kind of cross-inked polyethylene power cable, described inner sheath and oversheath adopt cross-linking polyethylene materials to make.
The utility model has following beneficial effect in sum: the utility model cable has the advantages such as the good and long service life of reasonable in design, insulation effect, described inner sheath and oversheath adopt cross-linking polyethylene materials to make, described crosslinked polyethylene is high, the nonpolar thermoplastic resin material of a kind of degree of crystallinity, there is good corrosion-resistant and water resistance, dielectric strength is high, and flexible laying, bring convenience to staff.

Embodiment
As shown in Figure 1, a kind of power cable with cross-linked polyethylene insulation, it comprises cable body 1, and described cable body 1 comprises conductor 2, insulating barrier 6, screen 7 and oversheath 11, and described cable body 1 inside is provided with multiple conductor 2; Described cable body 1 cross section is circular configuration; Described conductor 2 outer wrapping one deck protective sleeve 3; Described protective sleeve 3 and conductor 2 form cable core jointly; One deck insulating barrier 6 is set outside described cable core; Between described cable core and insulating barrier 6, gap portion is provided with multiple elasticity packing 4; The gap portion that described cable core, insulating barrier 6 and elasticity packing 4 are formed is provided with packed layer 5; Described insulating barrier 6 is outer closely extrudes one deck screen 7; Described screen 7 is extruded with heat-insulation layer 8 from inside to outside successively, block water twining package tape 9 and inner sheath 10; Described inner sheath 10 is outer closely extrudes one deck oversheath 11.
Described conductor 2 is stranded circular copper conductors structure of pressing, and described conductor 2 cross section 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; One deck protective sleeve 3 of described conductor 2 outer wrapping, can effectively protect conductor 2 by damage, to prevent conductor 2 from rupturing; Described packed layer 5 is glass cord or polypropylene fiber rope, makes cable body 1 internal structure compacter, prevents conductor 2 from occurring the situations such as skew; Described elasticity packing effectively can improve the structural strength of cable, improves the stretch-proof performance of cable; Described insulating barrier 6 effectively improves the insulation property of cable, and has stronger stability; Described screen 7 effectively can improve the anti-shielding performance of cable, prevents external electromagnetic signal from impacting cable; Described heat-insulation layer 8 is made for asbestos fibre material, can realize cable self insulation not-easy-to-freeze, decreases the probability of cable because damaging by low temperature; The described twining package tape 9 that blocks water can play the effect of radial waterproof and the infiltration of anti-chemical solution, and cable also can be worked long hours under rugged environment; Described inner sheath 10 and oversheath 11 adopt cross-linking polyethylene materials to make, described crosslinked polyethylene is high, the nonpolar thermoplastic resin material of a kind of degree of crystallinity, and have good corrosion-resistant and water resistance, dielectric strength is high, and flexible laying, bring convenience to staff.
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.
