Description
Technical field
The utility model relates to field of cables, particularly relates to a kind of acid/alkali-resistant water-proof cable.
Background technology
At present, along with the development of science and technology, no matter be industry or the daily life of the mankind, all towards electrified future development, cable is then in industry and power domain, its status is also raising gradually, the existing construction of cable comprises many conductors, be coated on the insulating barrier outside each conductor, several part such as braid and sheath, but the anti-external disturbance performance of the cable of this structure and envelope eapsulotomy poor, easily cause distorted signals, therefore Signal transmissions is very unstable, the image of transmission is also unintelligible, and existing cable humidity resistance is not fine, be easy to oxidized, and cable common under the environment of some strong acid and strong bases can not be effectively competent at, a very large difficult problem is brought to enterprise.
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 acid/alkali-resistant water-proof cable.
The utility model is taked following technical scheme to realize: a kind of acid/alkali-resistant water-proof 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; The inner space formed between many described conductors is provided with light unit; 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 is extruded with the bonding sheath of aluminum-polyethylene and metal armor layers from inside to outside successively; Extrude one deck outside described metal armor layers to block water wrapped belt; The described wrapped belt that blocks water closely extrudes one deck oversheath outward.
Above-mentioned a kind of acid/alkali-resistant water-proof cable, described conductor is closed by multiply nickel-clad copper skein silk and forms.
Above-mentioned a kind of acid/alkali-resistant water-proof cable, the light unit that described conductor center is arranged is monomode fiber or multimode fiber.
Above-mentioned a kind of acid/alkali-resistant water-proof cable, the filler between described conductor and insulating barrier is made up of non-wet materials polypropylene mesh split fibre.
Above-mentioned a kind of acid/alkali-resistant water-proof cable, described insulating barrier is made up of ceramic SiClx insulating material.
The utility model has following beneficial effect in sum: this cable has the advantages such as good shielding properties, acid-proof alkaline and long service life, described conductor forms by multiply tinned copper wire is stranded, not only substantially increase the operating efficiency of cable, also make its work more stable, and described conductor structure is easy to processing, making length is unrestricted, has certain flexibility and bendability during use, facilitates the laying of workpeople.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional structure schematic diagram;
Wherein: 1, cable body; 2, conductor; 3, light unit; 4, packed layer; 5, insulating barrier; 6, screen; 7, the bonding sheath of aluminum-polyethylene; 8, metal armor layers; 9, block water wrapped belt; 10, oversheath.
Embodiment
As shown in Figure 1, a kind of acid/alkali-resistant water-proof cable, 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; The inner space formed between many described conductors 2 is provided with light unit 3; 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 4; Described insulating barrier 5 is outer closely extrudes one deck screen 6; Described screen 6 is extruded with the bonding sheath 7 of aluminum-polyethylene and metal armor layers 8 from inside to outside successively; Extrude one deck outside described metal armor layers 8 to block water wrapped belt 9; The described wrapped belt 9 that blocks water is outer closely extrudes one deck oversheath 10.
Described conductor 2 adopts multiply nickel-clad copper skein silk to close and forms, and not only substantially increases the operating efficiency of cable, also makes 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; Packed layer 4 between described conductor 2 and insulating barrier 5 is made up of non-wet materials polypropylene mesh split fibre, substantially increase the working strength of cable body 1, make cable body 1 can bear larger pressure, effectively extend the useful life of cable body 1; The light unit 3 that described conductor 2 inside is arranged is monomode fiber or multimode fiber, not only makes the speed that diffuses information of cable faster, and is not easy to be subject to extraneous interference, the use of cable can be made more reliable and more stable, make the capacity of Information Communication larger; The insulating barrier 5 extruded outside described conductor 2 is made up of ceramic SiClx insulating material, when cable breaking out of fire, the insulating barrier that temperature raises can ceramic immediately, the pottery formed has good insulating properties and heat resistance, even if concrete on fire also can continue to use, without the need to changing, thus greatly save cost; The screen 6 extruded outside described insulating barrier 5 effectively raises the shielding properties of cable body 1, avoids the interference of signal, makes it use more stable; The outer bonding sheath 7 of aluminum-polyethylene arranged of described screen 6, thus the requirement reaching oil resistant anti-acid-base solution corrosion again, thus the fail safe substantially increasing that cable uses in the presence of a harsh environment; Described metal armor layers 8 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 good high temperature resistant and fire-retardant effect, cable also normally can be worked in the case of a high temperature, can effectively protect cable inner conductor to be damaged; The described wrapped belt 9 that blocks water not only can play the effect of waterproof, the infiltration of anti-chemical solution, also serves the effect of buffering ambient pressure; Described oversheath 10 has stronger heat-resisting ability, and can not be oxidized easily and occur crackle, can in rugged environment the long period use, reduce maintenance probability, make entreprise cost lower.
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.
