Description
Technical field
The utility model relates to field of cables, particularly relates to a kind of low temperature resistant stretch-proof power cable.
Background technology
At present, along with the development of science and technology, all trades and professions are all at the future development towards industrialization and electronization, this also means the increase greatly of cable consumption, but because the operational environment of its every profession and trade all has difference, also just require that the characteristic that cable possesses is different, just scientific and technological at present development, people require that cable is not only the single effect possessing transmission current, also want cable to a certain extent can be corrosion-resistant and low temperature resistant, but existing cable used on the market in use, these demands can not be met, under relatively rugged environment, general cable can not normally use, not only make troubles to user, also there are some potential safety hazards.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of low temperature resistant stretch-proof power cable.
The utility model is taked following technical scheme to realize: a kind of low temperature resistant stretch-proof power cable, 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 cable body center is provided with an elasticity packing; Described conductor closely extrudes a layer insulating outward; Between described insulating barrier and conductor, gap portion is provided with packed layer; Described insulating barrier closely extrudes one deck screen outward; Described screen extrudes alumilite process coating, the bonding sheath of aluminum-polyethylene and metal armor layers from inside to outside successively; Described metal armor layers closely extrudes one deck anticorrosive coat outward; Described anticorrosive coat closely extrudes one deck oversheath outward.
The low temperature resistant stretch-proof power cable of above-mentioned one, described conductor is even to outdiffusion centered by elasticity packing.
The low temperature resistant stretch-proof power cable of above-mentioned one, described conductor forms by multiply tinned copper wire is stranded, and described conductors cross is circular configuration.
The low temperature resistant stretch-proof power cable of above-mentioned one, described insulating barrier is inorganic thin film, PVC coating or elastomeric material are made.
The low temperature resistant stretch-proof power cable of above-mentioned one, described oversheath adopts butyronitrile pvc material to make.
The low temperature resistant stretch-proof power cable of above-mentioned one, described packed layer is made up of non-wet materials polypropylene mesh split fibre.
The utility model has following beneficial effect in sum: the utility model has the advantages such as reasonable in design, resistance to low temperature excellence and stretch-proof, the bonding sheath of described aluminum-polyethylene extrudes in cable inner, prevent the etchant solutions such as soda acid to the erosion of cable, effectively raise the fail safe that cable uses in the presence of a harsh environment, effectively extend the useful life of cable.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional structure schematic diagram;
Wherein: 1, cable body; 2, conductor; 3, packed layer; 4, elasticity packing; 5, insulating barrier; 6, screen; 7, alumilite process coating; 8, the bonding sheath of aluminum-polyethylene; 9, metal armor layers; 10, anticorrosive coat; 11, oversheath.
Embodiment
As shown in Figure 1, a kind of low temperature resistant stretch-proof power cable, it comprises cable body 1, and described cable body 1 comprises conductor 2, insulating barrier 5, screen 6 and oversheath 11, and described cable body 1 inside is provided with many conductors 2; Described cable body 1 center is provided with an elasticity packing 4; Described conductor 2 is outer closely extrudes a layer insulating 5; Between described insulating barrier 5 and conductor 2, gap portion is provided with packed layer 3; Described insulating barrier 5 is outer closely extrudes one deck screen 6; Described screen 6 extrudes alumilite process coating 7, the bonding sheath 8 of aluminum-polyethylene and metal armor layers 9 from inside to outside successively; Described metal armor layers 9 is outer closely extrudes one deck anticorrosive coat 10; Described anticorrosive coat 10 is outer closely extrudes one deck oversheath 11.
Described conductor 2 forms by multiply tinned copper wire is stranded, and described conductor 2 cross section is circular configuration, greatly can improve the electric conductivity of cable body 1, also makes the process of cable body 1 signal transmission more stable; The elasticity packing 4 that described cable body 1 center is arranged effectively can improve the elasticity of cable body 1, prevents cable because there is situation about rupturing by external force; Between described conductor 2 and insulating barrier 5, gap portion is provided with packed layer 3, described packed layer 3 is made up of non-wet materials polypropylene mesh split fibre, thus can effectively prevent cable body 1 inside from impacting it because entering moisture, there will not be the situation that cable makes moist, make the service behaviour of cable body 1 more stable, and make cable body 1 internal structure compacter; Described insulating barrier 5 is made for inorganic thin film, PVC coating or elastomeric material, not only increases the ampacity of cable body 1, also effectively raises the insulation property of cable, improves the result of use of cable; Described screen 6 can avoid cable to occur insulation breakdown phenomenon, reduces the interference of electromagnetism to cable simultaneously, improves the shielding properties of cable; Described alumilite process coating 7 has good extinction and heat-absorbing action, substantially increases the tolerance to cold of cable; The bonding sheath 8 of described aluminum-polyethylene extrudes in cable inner, prevents the etchant solutions such as soda acid to the erosion of cable, effectively raises the fail safe that cable uses in the presence of a harsh environment, effectively extend the useful life of cable; Described metal armor layers 9 substantially increases the structural strength of cable, extends the useful life of cable; Described anticorrosive coat 10 effectively prevents cable because using the corrosion phenomenon caused for a long time, effectively reduces entreprise cost; Described oversheath 11 adopts butyronitrile pvc material to make, thus has excellent acid-proof alkaline, effectively protects the internal structure 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.
