The utility model has the advantages of structural design is reasonable, effectual and long service life prevents attenuateing.
Description
Technical field
The utility model relates to field of cables, particularly relates to a kind of anti-decay industrial digital telecommunication cable.
Background technology
At present, along with the development of science and technology, people get more and more to the demand of electric wire, the development of every field all needs the participation of cable, and therefore the requirement of people to cable is more and more higher, traditional cable by arrange insulating barrier and screen make cable prevent it by external electromagnetic signal in the course of the work disturb, but cable is in the process of signal transmission, often occur that the decay of signal causes information dropout, bring very large problem, be badly in need of now solving this kind of problem.
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 anti-decay industrial digital telecommunication cable.
The utility model is taked following technical scheme to realize: a kind of anti-decay industrial digital telecommunication 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 aluminum skeleton; And described aluminum skeletal internal is provided with multiple conductor; And described aluminum skeletal internal is provided with multiple gum filler; Described aluminum skeleton outer wrapping one layer insulating; Described insulating barrier closely extrudes one deck screen outward; One deck flame resistant protective layer is extruded outside described screen; One deck passivation layer is extruded outside described flame resistant protective layer; One deck oversheath is extruded outside described passivation layer.
Above-mentioned one anti-decay industrial digital telecommunication cable, described conductor employing nickel-clad copper monofilament is stranded to be formed.
Above-mentioned one anti-decay industrial digital telecommunication cable, between described insulating barrier and aluminum skeleton, gap portion is provided with reinforced layer.
Above-mentioned one anti-decay industrial digital telecommunication cable, described flame resistant protective layer is that crosslinked polyethylene tension rubber is made.
Above-mentioned one anti-decay industrial digital telecommunication cable, described oversheath is that PVC material is made.
The utility model has following beneficial effect in sum: the utility model has the advantages such as the effective and long service life of reasonable in design, anti-decay, described oversheath is that PVC material is made, described PVC is a kind of polymeric material of vinyl, its material is a kind of amorphism material, there is the characteristics such as nonflammable, high temperature resistant and weatherability change, 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, aluminum skeleton; 4, gum filler; 5, reinforced layer; 6, insulating barrier; 7, screen; 8, flame resistant protective layer; 9, passivation layer; 10, oversheath.
Embodiment
As shown in Figure 1, a kind of anti-decay industrial digital telecommunication cable, it comprises cable body 1, and described cable body 1 comprises conductor 2, insulating barrier 6, screen 7 and oversheath 10, and described cable body 1 inside is provided with aluminum skeleton 3; And described aluminum skeleton 3 inside is provided with multiple conductor 2; And described aluminum skeleton 3 inside is provided with multiple gum filler 4; Described aluminum skeleton 3 outer wrapping one layer insulating 6; Described insulating barrier 6 is outer closely extrudes one deck screen 7; One deck flame resistant protective layer 8 is extruded outside described screen 7; One deck passivation layer 9 is extruded outside described flame resistant protective layer 8; One deck oversheath 10 is extruded outside described passivation layer 9.
Described conductor 2 adopts that nickel-clad copper monofilament is stranded to be formed, and not only makes the pliability of cable increase, and makes it more easily lay, and is suitable for mobile more occasion, ensure that the safety of equipment; Aluminum skeleton 3 fixed conductor 2 that described cable body 1 inside is arranged and gum filler 4, effectively prevent conductor 2 and gum filler 4 from occurring the situation of skew, make its course of work more stable; Described aluminum skeleton 3 makes the transmission consumption of cable drop to minimum, decreases echo damage, characteristic impedance and crosstalk attenuation simultaneously, prevents cable from the process of signal transmission, occurring situation about decaying; Described reinforced layer 5 makes cable body 1 internal structure more tight; Described flame resistant protective layer 8 is made for crosslinked polyethylene tension elastomeric material, has good high temperature high voltage resistant performance, and cable also can normally be worked under rugged environment; Described passivation layer 9 can make cable be embedded in underground for a long time, and protection cable body 1 there will not be the situation of corrosion, also can not be oxidized; Described oversheath 10 is made for PVC material, and described PVC is a kind of polymeric material of vinyl, and its material is a kind of amorphism material, has the characteristics such as nonflammable, high temperature resistant and weatherability change, extends 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.
