Abstract
The invention discloses a multi-core moistureproof and corrosion-proof cable, comprising a cable body that includes an insulating layer, a plurality of conductors, a shielding layer and an outer sheath. The cross section of the cable body is circular in shape; the plurality of conducts which are of independent structures are arranged in the cable body; a layer of corrugated pipe is arranged outside the conductors; the insulating layer is extruded outside the corrugated pipe; the gap part between the corrugated pipe and the insulating layer is filled with waterproof ropes; the shielding layer is tightly extruded outside the insulating layer; the shielding layer sequentially include a waterproof layer and an armor layer from inside to outside; a plurality of drainage cores are arranged in the waterproof layer; the outer sheath is tightly extruded outside the armor layer. The cable is good in shielding performance and bend-resistant performance, high in conductivity, and meanwhile has the performance of high pressure resistance and moisture resistance.
Description
Technical field
The present invention relates to field of cables, particularly relate to a kind of multicore Moisture-proof corrosion-resistant cable.
Background technology
At present, along with the fast development of science and technology, all trades and professions are all at made rapid progress, and cable as the cable often used in industry especially by people's extensive use, by the cable transmission signal of telecommunication, because of its steady signal transmission and easy to use favor by people, but because the operational environment of different industries is different, the requirement of cable is also not quite similar, the field that a few thing environment is comparatively special, often there is high temperature or the larger situation of humidity, part steam enters cable inside by cable, thus cause the loss of signal, seriously system short-circuit can be caused, bring very large trouble, the useful life of cable is reduced, increase entreprise cost.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of multicore Moisture-proof corrosion-resistant cable.
The present invention takes following technical scheme to realize: a kind of multicore Moisture-proof corrosion-resistant cable, and it comprises cable body, and described cable body comprises insulating barrier, conductor, screen and oversheath, and described cable body cross section is circular configuration; Described cable body inside is provided with many conductors; And be absolute construction between described conductor; One deck bellows is set outside described conductor; A layer insulating is extruded outside described bellows; Gap portion between described bellows and insulating barrier is filled with waterproofing rope; Described insulating barrier closely extrudes one deck screen outward; Described screen is extruded with watertight composition and armour from inside to outside successively; Described watertight composition inside is provided with many guide cores; Described armour closely extrudes one deck oversheath outward.
Above-mentioned a kind of multicore Moisture-proof corrosion-resistant cable, to be that tinned copper wire is stranded form the conductor that described cable body inside is arranged.
Above-mentioned a kind of multicore Moisture-proof corrosion-resistant cable, the waterproofing rope that between described bellows and insulating barrier, gap portion is arranged is the rope shape materials be composited by polyester fiber, adhesive and water-absorbing resin.
Above-mentioned a kind of multicore Moisture-proof corrosion-resistant cable, described armour is woven by stainless steel wire to form, and be square grid shape structure.
Above-mentioned a kind of multicore Moisture-proof corrosion-resistant cable, described insulating barrier, Thickness Ratio between screen and watertight composition are 1:1:1.
The present invention has following beneficial effect in sum: this cable has good shielding properties, resist bending performance, conductance is high, also there is the performances such as high pressure resistant and moistureproof simultaneously, because of the moisture of temperature generation when the watertight composition extruded in described cable body is conducive to absorbing, store and discharge the work of conductor dissymmetry, prevent moisture from entering cable body inside, cause the short circuit of system, make the use of cable convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Wherein: 1, cable body; 2, conductor; 3, bellows; 4, waterproofing rope; 5, insulating barrier; 6, screen; 7, watertight composition; 8, armour; 9, oversheath; 10, guide core.
Embodiment
As shown in Figure 1, a kind of multicore Moisture-proof corrosion-resistant cable, it comprises cable body 1, and described cable body 1 comprises insulating barrier 5, conductor 2, screen 6 and oversheath 9, and described cable body 1 cross section is circular configuration; Described cable body 1 inside is provided with many conductors 2; And be absolute construction between described conductor 2; Outside described conductor 2, one deck bellows 3 is set; A layer insulating 5 is extruded outside described bellows 3; Gap portion between described bellows 3 and insulating barrier 5 is filled with waterproofing rope 4; Described insulating barrier 5 is outer closely extrudes one deck screen 6; Described screen 6 is extruded with watertight composition 7 and armour 8 from inside to outside successively; Described watertight composition 7 inside is provided with many guide cores 10; Described armour 8 is outer closely extrudes one deck oversheath 9.
Described conductor 2 forms by tinned copper wire is stranded, thus have good electric conductivity, and operationally transmission of electric signals is more stable to make cable body 1, and described conductor 2 is absolute construction, there will not be the situation of interference mutually; The outer bellows 3 arranged of described conductor 2 can effectively protect conductor 2 can not easily disturb by the external world, make its longer service life; The gasket for packing 4 arranged between described conductor 2 and insulating barrier 5 is that the rope shape materials be composited by polyester fiber, adhesive and water-absorbing resin is formed, can play and prevent the globule from invading cable from radial direction, the water resistance of protection cable, make cable can the larger environmental work of humidity ratio, extend the service life of cable simultaneously, reduce maintenance cost; Described insulating barrier 5 can improve the ampacity of cable body 1, improves the ambient temperature that cable body 1 bears; Described screen 6 can avoid insulation breakdown phenomenon, reduces outside electromagnetic interference, improves the shielding properties of cable body 1; Because of the moisture that temperature produces when described watertight composition 7 is conducive to absorbing, store and discharge the work of conductor 2 dissymmetry, prevents moisture from entering cable body 1 inner, cause the short circuit of system, make the use of cable convenient; Described armour 8 adopts stainless steel wire to weave and forms, and is square grid shape structure, thus the effective mechanical strength strengthening cable body 1, ensure that the stretch-proof performance of cable; The many guide cores 10 that described watertight composition 7 inside is arranged can improve the conductive effect of conductor 2; Described oversheath 9 can improve the antiwear property of cable body 1, avoids to a certain extent making conductor 2 damaged because it is subject to larger impulsive force, and the internal structure of protection cable body 1, makes its longer service life.
The above is the embodiment of the present invention, therefore all equivalences done according to structure, feature and the principle described in the present patent application scope change or modify, and are included in patent claim of the present invention.
