Abstract
The utility model discloses a composite cable which is provided with a perfluorinated ethylene-propylene copolymer insulating sleeve protection layer, a braided shield layer, a polyester insulating layer and an aluminum foil layer which are sequentially arranged from outside to inside, wherein a master ground wire is also arranged between the braided shield layer and the polyester insulating layer. The composite cable has lower cost and more excellent performances and can work normally and reliably in case of urgent large currents.
Description
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.In addition, total ground wire that existing composite cable is adopted, its rated current is scheduled to, and when the big electric current of burst, burns total ground wire easily.
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 is provided with fluorinated ethylene propylene copolymer insulating sleeve protective layer, woven shield, polyester insulated layer and aluminium foil layer from outside to inside successively; Also be provided with a total ground wire between described woven shield and the polyester insulated layer.
In the such scheme, be provided with the glass fiber bundle that a communication recombination line, two twisted-pair feeders and Duo Gen are used to strengthen in the described aluminium foil layer; Described communication recombination line comprises two cables that are arranged side by side, a communication ground wire and is coated on these two cables and communication ground wire screen outward; Described twisted-pair feeder comprises two cables that twist together; Described each cable is provided with by stranded cable core that forms of multiple conducting wires and fluoroplastic insulation layer successively along direction from inside to outside.
In the such scheme, described polyester insulated layer is attached to the rete on the aluminium foil layer outer wall.
In the such scheme, the used copper material of described woven shield is tinned copper wire or zinc-plated copper strips.
In the such scheme, described communication recombination line is arranged on the middle and upper part of aluminium foil layer enclosed space, and described two twisted-pair feeders are positioned at the both sides, middle part of aluminium foil layer enclosed space, and are symmetrical set, described total ground wire be positioned at described communication recombination line under.
In the such scheme, described total ground wire and communication ground wire are provided with by stranded cable core that forms of multiple conducting wires and plastic insulating layer successively along direction from inside to outside.
The utlity model has positive effect: in (1) the utility model,, effectively reduce each circuit signal each other and disturb, make it have comparatively good interference free performance by the position relation of reasonable Arrangement communication recombination line, twisted-pair feeder and total ground wire; In addition, by total ground wire is arranged between woven shield and the aluminium foil layer, when big electric current passes through, total ground wire temperature raises, until making the polyester insulated layer segment on the aluminium foil outer wall or all melting, make ground wire can with the direct conducting of aluminium foil, thereby make big electric current also can pass through smoothly, effectively reduce the possibility of burning whole circuit because of the big electric current that happens suddenly.
