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 smoke and zero halogen fire-proof high-temperature resistant Industry Control cable.
The utility model is taked following technical scheme to realize: a kind of low smoke and zero halogen fire-proof high-temperature resistant Industry Control cable, and it comprises cable body, conductor, insulating barrier, screen and oversheath, is provided with some conductors in described cable body; Described conductors cross is circular configuration; Described conductor is outside equipped with one deck core protective layer; Described core protective layer is outside equipped with some Al-alloy metal flexible pipes; Described core protective layer is outside equipped with insulating barrier; Between described insulating barrier and core protective layer, gap portion is provided with filler; One deck screen is extruded outside described insulating barrier; Described screen is disposed with armour and coat of metal from inside to outside; Many guide cores are provided with in described coat of metal; Described coat of metal intimate surface extrudes one deck inner sheath; Described oversheath is arranged at inner sheath surface; Described conductor adopts real core conductor or multiply to press twisted copper conductors and makes; Described filler is made up of non-net polypropylene tearing material of opening; Described armour wrappedly to form by strands of metal wire is stranded; Described coat of metal material is medium and low carbon steel or low-alloy steel; Described oversheath adopts any one material in smoke halogen-free flame-proof plastic for low polyvinyl chloride or corrosion-inhibiting coating to be made.
Owing to have employed such scheme, compare with prior art, the utility model has following beneficial effect:
1, described filler employing is non-opens net polypropylene tearing material, thus can reduce the heat absorption capacity coefficient of material, presses structure and reduces construction of cable part thermal resistivity, cable dissipate heat effect is increased, effectively can prevent the overheated burning of cable by densification.
2, the armour that described screen is arranged outward improves the protective value of cable; enhance the resistance to compression resistance to tension of cable, thus extend the useful life of cable, and armour cross section is circular configuration; make the global shape very rounding of cable, structure is more stable.
3, the coat of metal arranged in described cable body, effectively can strengthen the bulk strength of cable, makes cable can bear larger load and External Force Acting, and effectively can prevent the animal bites bad cable of mouse and so on, for cable provides better protection.
4, described conductor adopts real core conductor or multiply to press twisted copper conductors to make, greatly can improve the electric conductivity of cable, also make cable more stable by the process of conductor propagation signal, and multiply copper conductor can effectively make conductor have stronger stretch-proof performance, can not rupture easily.
5, described oversheath adopts smoke halogen-free flame-proof plastic for low polyvinyl chloride or corrosion-inhibiting coating, higher temperature can be born, and harmful Substances Pollution environment can not be produced in hot environment, thus make its environmental-protecting performance more excellent, meet present the advocated environmental protection concept of people.
