Abstract

The utility model relates to a cable, especially to an armoured low temperature-resistant tension cable that is used for multi-path electrical signal transmission and is applied to fields like a mine, a coal mine, and a sensor and the like. Each of cable cores is formed by seven 0.2-mm tinned copper wire beam conductors and one butyronitrile polyethylene insulating layer, wherein the butyronitrile polyethylene insulating layer is arranged outside the seven 0.2-mm tinned copper wire beam conductors. Polypropylene fillers are added among the four cable cores to form the cable. And the following layers and components are successively arranged outside the cable cores and the fillers: a copper strip shielding layer with the 20-mm width and the 0.5-mm thickness being wound, three 0.5-mm tinned copper ground wires being longitudinally arranged, an inner sheath being extruded, a 1.0-mm armoured layer being braided, and a butyronitrile polyethylene sheath with temperature toleration being coated, wherein the armoured layer is foxed by zinc-coated wires. According to the utility model, the beneficial effects of the cable are as follows: the overall tensile property of the cable is improved; the electrical property is excellent and the conductors can be bent easily, thereby realizing the good flexibility; the chemical resistant property and the temperature toleration are good, thereby improving the service life of the cable and realizing good flame resistance; the anti-electromagnetic interference capability of the cable is improved and thus the communication stability is good; and the manufacturability is good.

Description

The low temperature resistant tensile cable of armouring

Technical field

The utility model relates to a kind of cable, particularly a kind of low temperature resistant tensile cable of armouring for mine, colliery, sensor field weatherability multipath electric signal transmission use.

Background technology

In modern industry, the effect that cable plays is transmitted except signal, and electric power even can play drag interaction outside supplying with and controlling, and can effectively save the space like this, reduce the pulling force components and parts, but the composite performance index to cable is more and more higher like this.The sensor cable that in the past used, use polyethylene, polyvinyl chloride more, as insulating material, these materials are often simple at the stranded rear braiding aramid fiber yarn of heart yearn, will cause like this cable discontinuity to occur in the load-bearing process, the special purposes such as intensity and signal attenuation index and high and low temperature resistance are all undesirable, finally cause the fracture of cable and equipment connection or cable performance to reduce, the transformer cable of existing domestic production exists oil resistance poor, heatproof is low, the defectives such as Tensile strength is inadequate, impact is normally used.

Summary of the invention

In view of domestic deficiency to above-mentioned cable imbalance between supply and demand and prior art existence, the utility model provides a kind of fine polythene material of fourth that adopts as the low temperature resistant tensile cable of armouring of insulation and sheath, and the design of structure can reach the market instructions for use fully.

the utility model for achieving the above object, the technical scheme that adopts is: the low temperature resistant tensile cable of a kind of armouring, it is characterized in that: be included in 7 strands of 0.2mm tin-coated copper synnema conductors and be provided with the cable core that the fine polyethylene layer of one deck fourth consists of outward, also comprise inserts, screen, ground wire, inner sheath, armour, oversheath, add polypropylene inserts stranding in four described cable cores, being wound around successively one deck width outside it is that the thick width of 20mm is the copper strip shielding layer of 0.5mm, the vertical tinned wird ground wire of putting three 0.5mm, extrude one deck inner sheath, the armour that braiding one deck 1.0mm zinc-coated wire consists of, the fine outer protective polyethylene cover of the parcel durothermic fourth of one deck.

The beneficial effects of the utility model are: 1, improved the whole cable tensile property, galvanized steel wire has solved the problem of cable tension, has also increased the jamproof ability of screen simultaneously.2, performance is excellent: inner wire is that 7 strands of 0.2mm tinned copper wires are stranded, and electrical property is excellent, and conductor is easily crooked, and flexibility is good.3, chemical-resistance is good: oversheath adopts the fine polythene material of heatproof fourth, improves the ability of cable oil resistant chemical-resistant reagent.4, temperature tolerance is good, the fine polythene material temperature resistant grade of heatproof fourth is brought up to 125 ℃ by 70 ℃, can work long hours in the environment of-40 ℃ to 90 ℃, improve useful life 5, good flame resistance: adopt the fine polythene material of heatproof fourth to make sheath, had very high fire resistance.6, Electro Magnetic Compatibility: the structure that bare copper strip is wound around, the anti-electromagnetic interference capability of raising product.7, communication is stable: Cable Construction Design stable makes the communication index such as inductance capacitance cross-talk stable.8, good manufacturability: ripe production corollary equipment, use general cabling device and extrusion equipment just can realize, convenient and simple high efficiency.
