Technical field
The utility model belongs to composite cable structure-design technique field.
Background technology
Electric wire is the carrier that electric power is carried or information is transmitted, and is widely used in industry and the civilian electricity consumption facility.Environment for use or occasion difference require different.Especially industry environments for use such as wind power generation, metallurgy and chemical industry are abominable, and cable product is proposed some specific performance properties requirements.Require low temperature resistant, the antitorque commentaries on classics of cable as wind power plant, metallurgy industry requires cable high temperature resistant, corrosion-resistant, and chemical industry requires acidproof, the oil resistant, corrosion-resistant of cable.And the PVC sheath material flexibility of current use is poor, elongation at break is little, anti-cracking performance is poor, do not possess reverse, the performance of anti-subzero 40 ℃ of low temperature or anti-110 ℃ of high temperature, oil resistant, acidproof, Corrosion Protection do not reach requirement yet, cable is short useful life, changes frequently, influences industrial production and normally carries out.In order to satisfy these specific (special) requirements, some producer has to adopt silicon rubber or polyurethane material, but the resistance to impact of silicon rubber is poor, and cable cover(ing) ftractures easily, and useful life is also short, and the cost of polyurethane material is too high.So still having, the structure of existing electric wire and material selection thereof need improvements badly.
Summary of the invention
The purpose of this utility model provides the composite cable that a kind of cost is lower and performance is comparatively good.
The technical scheme that realizes the utility model purpose is: a kind of composite cable, comprise that its outermost layer is the looped wrap protective layer, its design feature is: described looped wrap protective layer is made by fluorinated ethylene propylene copolymer, be provided with ring-type teflon insulation layer in the described sheath protective layer, be provided with a plurality of cables in the described teflon insulation layer, described each cable is provided with the perfluoroethylene-propylene insulating barrier and from outside to inside successively as the cable core of conductor; Have at least two cable twistings to be integral in all cables, and the outside of these two cables is provided with screen and the perfluoroethylene-propylene insulating barrier that is entwined by copper material successively along direction from inside to outside, stranded formula signal transmission passage of the common composition of these two cables and screen thereof and insulating barrier; Have at least edge, the outside direction from inside to outside of an independent cable to be provided with screen and the fluorinated ethylene propylene copolymer insulating barrier that is entwined by copper material successively in all cables, single line coaxial-type signal transmission passage of the common composition of this cable and screen thereof and insulating barrier.
In the such scheme, be provided with seven cables in the described teflon insulation layer, described stranded formula signal transmission passage is arranged on the middle and upper part of composite cable, described single line coaxial-type signal transmission passage be arranged on the middle and lower part of described stranded formula signal transmission passage and be positioned at described stranded formula signal transmission passage under; All the other four cables are symmetrical arranged in twos.
In the such scheme, the used copper material of described screen is tinned copper wire or zinc-plated copper strips.
The utlity model has positive effect: in (1) the utility model, be provided with ring-type teflon insulation layer in the described sheath protective layer, be provided with a plurality of cables in the described teflon insulation layer, described each cable is provided with the perfluoroethylene-propylene insulating barrier and from outside to inside successively as the cable core of conductor; There are two cable twistings to be integral in all cables, and the outside of these two cables is provided with screen and the perfluoroethylene-propylene insulating barrier that is entwined by copper material successively along direction from inside to outside, stranded formula signal transmission passage of the common composition of these two cables and screen thereof and insulating barrier; There is edge, the outside direction from inside to outside of an independent cable to be provided with screen and the fluorinated ethylene propylene copolymer insulating barrier that is entwined by copper material successively in all cables, single line coaxial-type signal transmission passage of the common composition of this cable and screen thereof and insulating barrier; The composite cable of this structure is owing to adopt fluorinated ethylene propylene copolymer to make, and layer is provided with ring-type teflon insulation layer within it, thereby compare with adopting layer of polyurethane, price is comparatively cheap, and has better acidproof, oil resistant, heatproof, decay resistance.In addition, the composite cable of this kind structure adds the twisted-pair feeder and the single cord of shielding by setting, can be with it as signalling channel, and again in conjunction with all the other common cables, thereby make and the utlity model has excellent multi channel signals transportation performance.The utility model is particularly useful for the transmission of many signals, can use separately, also can many side by side or stranded use.
