Description
Technical field
The utility model relates to field of cables, particularly relates to a kind of crosslinked polyethylene moisture-resisting water-proof industrial cable.
Background technology
At present, along with the development of science and technology, people are also increasing to the demand of cable, and general cable mainly comprises conductor, insulating barrier and oversheath, but this structure is comparatively simple, can only use under general operational environment, but along with the difference of operational environment, people are also improving greatly to the requirement of cable, such as under the environment that some are moister, general cable after a long time use, moisture in air can penetrate into cable inside, thus the insulating barrier causing cable inside to arrange is breakdown, serious curtailment useful life of cable, considerably increase entreprise cost, also potential safety hazard can be there is.
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 crosslinked polyethylene moisture-resisting water-proof industrial cable.
The utility model is taked following technical scheme to realize: a kind of crosslinked polyethylene moisture-resisting water-proof industrial cable, it comprises cable body, described cable body comprises conductor, insulating barrier, screen and oversheath, and described cable body inside is provided with many conductors; Described conductor closely wraps up one deck protective sleeve outward; Described protective sleeve and conductor form cable core jointly; Described cable core closely extrudes a layer insulating outward; Gap portion between described insulating barrier and cable core is provided with multiple guide core; And described guide core respectively with insulating barrier and cable core tangent; Described cable core, gap portion between insulating barrier and guide core are provided with packed layer; Described insulating barrier closely extrudes one deck screen outward; Described screen is extruded with coat of metal, water blocking layer and armour from inside to outside successively; Described armour closely extrudes one deck oversheath outward.
Above-mentioned a kind of crosslinked polyethylene moisture-resisting water-proof industrial cable, described conductor is closed by multiply nickel-clad copper skein silk to form.
Above-mentioned a kind of crosslinked polyethylene moisture-resisting water-proof industrial cable, described insulating barrier is made up of cross-linking polyethylene materials.
Above-mentioned a kind of crosslinked polyethylene moisture-resisting water-proof industrial cable, described coat of metal is formed by three layers of zinc-coated wire armouring.
Above-mentioned a kind of crosslinked polyethylene moisture-resisting water-proof industrial cable, described packed layer material is glass cord.

The utility model has following beneficial effect in sum: the utility model cable has the advantages such as excellent water proofing property, anticorrosive property and long service life, described oversheath is made up of butyronitrile pvc material, described polythene material is high, the nonpolar thermoplastic resin material of a kind of degree of crystallinity, there is good corrosion resistance and water vapor performance, dielectric strength is high, and flexible, the laying for staff provides conveniently.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional structure schematic diagram;
Wherein: 1, cable body; 2, conductor; 3, protective sleeve; 4, guide core; 5, packed layer; 6, insulating barrier; 7, screen; 8, coat of metal; 9, water blocking layer; 10, armour; 11, oversheath.
Embodiment
As shown in Figure 1, a kind of crosslinked polyethylene moisture-resisting water-proof industrial cable, 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 many conductors 2; Described conductor 2 outer closely parcel one deck protective sleeve 3; Described protective sleeve 3 and conductor 2 form cable core jointly; Described cable core closely extrudes a layer insulating 6 outward; Gap portion between described insulating barrier 6 and cable core is provided with multiple guide core 4; And described guide core 4 respectively with insulating barrier 6 and cable core tangent; Described cable core, gap portion between insulating barrier 6 and guide core 4 are provided with packed layer 5; Described insulating barrier 6 is outer closely extrudes one deck screen 7; Described screen 7 is extruded with coat of metal 8, water blocking layer 9 and armour 10 from inside to outside successively; Described armour 10 is outer closely extrudes one deck oversheath 11.
Described conductor 2 is closed by multiply nickel-clad copper skein silk to form, and not only increases the anti-fracture ability of conductor 2, and have very excellent electric conductivity, effectively raise operating efficiency; The outer protective sleeve 3 arranged of described conductor 2 effectively protects conductor 2, makes conductor 2 there will not be the situation of fracture when being subject to external force; Described guide core 4 effectively raises the current capacity of cable; Described packed layer 5 material is glass cord, makes cable body 1 internal structure comparatively compact; Described insulating barrier 6 is made up of cross-linking polyethylene materials, thus make cable have good mechanical and physical performance and the dry and cracked performance of environmental stress resistance, can bear concentrated mechanical stress; Described screen 7 effectively raises the shielding properties of cable, prevents outer signals from causing interference to cable; Described coat of metal 8 is formed by three layers of zinc-coated wire armouring, thus can strengthen the bulk strength of cable, enables cable bear larger load and External Force Acting; Described water blocking layer 9 can avoid moisture to enter cable inside, prevent cable entered inner moisture corrode; Described armour 10 can strengthen the stretch-proof performance of cable further; Described oversheath 11 is made up of butyronitrile pvc material, has excellent acid-proof alkaline, prevent some harmful substances from causing erosion to cable, effectively extend the useful life of cable.
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.
