Background technology
At present; along with the development of science and technology; the demand of people to cable also gets more and more; cable is a kind of common data-signal transmission equipment; have that message capacity is large, transmission stability is high and the advantage such as security performance is good; but existing cable covering uses some comparatively general polymer; not only useful life is short; and the situation of contaminated environment can be there is; and partial cables because of its structural design unreasonable; work under the condition that environment is more severe and be easy to occur the situation of fracture, useful life is shorter, can not meet the needs of people.
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 anticorrosion stretch-proof shielded type cable.
The utility model is taked following technical scheme to realize: a kind of anticorrosion stretch-proof shielded type 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 conductor outer wrapping layer of glass pipe; Described fiberglass pipe and conductor form cable core jointly; Described cable core outer wrapping one layer insulating; Between described insulating barrier and cable core, gap portion is provided with packed layer; One deck screen is extruded outside described insulating barrier; One deck foil shielding layer is extruded outside described screen; Described foil shielding layer inside is provided with multiple polyolefin elastomer; One deck armour is extruded outside described foil shielding layer; Layer of metal braid is extruded outside described armour; One deck oversheath is extruded outside described wire sheathing.
Above-mentioned a kind of anticorrosion stretch-proof shielded type cable, to be that many tin-coated copper tow are stranded form described conductor.
Above-mentioned a kind of anticorrosion stretch-proof shielded type cable, the armour that described cable body inside is arranged is that heat-resistant aluminium alloy material is made;
Above-mentioned a kind of anticorrosion stretch-proof shielded type cable, described wire sheathing is wound around by nonmagnetic metal band or wire to make.
Above-mentioned a kind of anticorrosion stretch-proof shielded type cable, described insulating barrier, Thickness Ratio between screen and foil shielding layer are 1:1:1.
Above-mentioned a kind of anticorrosion stretch-proof shielded type cable, described oversheath adopts acrylonitrile-butadiene rubber or polyvinyl fluoride compound to make.
The utility model has following beneficial effect in sum: this cable has the advantages such as the good and long service life of reasonable in design, Corrosion Protection, described oversheath adopts acrylonitrile-butadiene rubber or polyvinyl fluoride compound to make, the oversheath of cable is made to have excellent decay resistance, through exposing to the weather for a long time, its mechanical performance does not change, and ensure that the element of cable inside is not etched.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional structure schematic diagram;
Wherein: 1, cable body; 2, conductor; 3, fiberglass pipe; 4, packed layer; 5, insulating barrier; 6, screen; 7, foil shielding layer; 8, polyolefin elastomer; 9, armour; 10, wire sheathing; 11, oversheath.
Embodiment
As shown in Figure 1, a kind of anticorrosion stretch-proof shielded type 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 conductor 2 outer wrapping layer of glass pipe 3; Described fiberglass pipe 3 and conductor 2 form cable core jointly; Described cable core outer wrapping one layer insulating 5; Between described insulating barrier 5 and cable core, gap portion is provided with packed layer 4; One deck screen 6 is extruded outside described insulating barrier 5; One deck foil shielding layer 7 is extruded outside described screen 6; Described foil shielding layer 7 inside is provided with multiple polyolefin elastomer 8; One deck armour 9 is extruded outside described foil shielding layer 7; Layer of metal braid 10 is extruded outside described armour 9; One deck oversheath 11 is extruded outside described wire sheathing 10.
Described conductor 2 forms for many tin-coated copper tow are stranded, not only substantially increases the operating efficiency of cable, also makes its work more stable, and have certain flexibility and bendability when conductor 2 uses, facilitate the laying of workpeople; The fiberglass pipe 3 of described conductor 2 outer wrapping has stronger tensile strength, and lightweight, and flexibility is good, cable deadweight and ambient pressure effectively can be prevented the destruction of cable, effectively protect conductor 2; Described packed layer 4 makes cable body 1 internal structure more compact, prevents conductor 2 from the situation of skew occurring; Described insulating barrier 5 effectively can improve the insulation property of cable body 1; Described screen 6 can avoid cable body 1 inside to produce insulation breakdown phenomenon, reduces the interference of external electromagnetic simultaneously; Described foil shielding layer 7 enhances cable and keeps out extraneous electromagnetic interference capability, improves the anti-shielding performance of cable body 1; Described polyolefin elastomer 8 effectively raises the elastic strength of cable, makes the more resistance to bending of cable; Described armour 9 is made for heat-resistant aluminium alloy material, because heat-resistant aluminium alloy material possesses certain fire protecting performance, fireproofing of cable performance is further strengthened, and it is inner effectively to stop moisture to enter cable body 1; Described wire sheathing 10 is wound around by nonmagnetic metal band or wire to make, and not only increases the structural strength of cable, also improve the electromagnetism interference performance of cable; Described oversheath 11 adopts acrylonitrile-butadiene rubber or polyvinyl fluoride compound to make, and make the oversheath 11 of cable have excellent decay resistance, through exposing to the weather for a long time, its mechanical performance does not change, and ensure that the element of cable inside is not etched.
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.
