Abstract
The utility model discloses a heat-resistant anti-corrosion shielded cable used for an intelligent instrument, which pertains to the technical field of cables. The heat-resistant anti-corrosion shielded cable comprises a cable core and a sheath, wherein the cable core consists of four small cables, heat-resistant and flame-retardant glass fiber filler yarns are filled in the gaps of the cable core formed by the four small cables, a polyimide film belt is lapped on the cable core and provided with a compound shielding layer formed by an aluminum-plastic shielding belt and a tin-plated shielding screen, and each small cable is formed by lapping a polyimide film belt on a twisted pair insulating wire and then braiding a tin-plated shielding screen on the lapped polyimide film belt. A conductor is formed by bundling a plurality of tin-plated soft copper wires, and an insulating layer is made of cross-linked polyolefin insulating material irradiated at 150 DEG C. The twisted pair insulating wires of the four small cables can be colored differently so as to be distinguished conveniently. The sheath is made of fluorinated ethylene propylene plastic. The heat-resistant anti-corrosion shielded cable has reasonable and simple structure, uses material scientifically, is easy to manufacture, has low cost and good using performance, and has the advantages of heat resistance, chemical corrosion resistance, good shielding effect, high anti-interference capability and the like.
Description
Technical field
The utility model relates to a kind of cable, and especially intelligent instrumentation belongs to the cable technology field with the structure of cable.
Background technology
Along with continuous progress in science and technology, intelligent instrument is fast-developing in recent years, and is used widely in a lot of industries, as heavy industry such as oil, chemical industry, iron and steel, electric power, metallurgy, drives the intelligent instrumentation cable thus and also constantly increases.In many industries, operational environment becomes increasingly complex, as high low temperature, chemical corrosion, strong jamming or the like, more existing instrument and meter cables can not adapt to the operational environment requirement, develop high-low temperature resistant, resistance to chemical attack, high flame retardant, ageing-resistant instrument and meter cable, satisfying the demand in market, is a urgent task of cable R﹠D institution and manufacturing enterprise.
The utility model content
The purpose of this utility model is exactly for satisfying the needs in market, a kind of high-low temperature resistant, resistance to chemical attack, high flame retardant, ageing-resistant intelligent instrument heat-resisting and anticorrosive shielded type cable being provided.
The purpose of this utility model is to realize by the improvement to existing cable, intelligent instrument heat-resisting and anticorrosive shielded type cable, comprise cable core and sheath, it is characterized in that described cable core is provided with four little cables, by the glass fibre gasket for packing of filling heat-resistant fireproof in the cable core gap of four little cable strandings, wrapped polyimide film band on the cable core is provided with by the plastic-aluminum mask tape on the polyimide film band and adds the composite shielding layer that the tin plated wire gauze screen constitutes; Described four little cables are respectively by wrapped polyimide film band on the pair twist insulated wire, and braiding tin plated wire gauze screen constitutes on wrapped polyimide film band.
Described insulated wire is made of conductor and insulating barrier, and conductor is that the zinc-plated soft copper tow of multiply closes, and insulating barrier is 150 ℃ of cross-linking radiation polyolefin insulation materials, and conductor extrudes 150 ℃ of cross-linking radiation polyolefin insulation materials outward.
The pair twist insulated wire of described four little cables is provided with the color of being convenient to distinguish.
The material of described sheath is a polyfluorinated ethylene plastic, and polyfluorinated ethylene plastic is extruded on the composite shielding layer.
The utility model is rational in infrastructure simple, and the science the selection of material is manufactured easily, and cost is low, and serviceability is good.Conductor adopts the zinc-plated soft copper tow of multiply to close, and makes conductor oxidative phenomena can not take place.Conductor extrudes 150 ℃ of cross-linking radiation polyolefin insulations outward, adopts cross-linking radiation technology, electrical property that the assurance insulating barrier is good and machinery, ageing properties.Four pairs of pair twist insulated wires of four little cables, all wrapped polyimide film band behind the insulated wire pair twist with high temperature resistant character, this material still can keep its good characteristic more than 200 ℃, and four pairs of pair twist insulated wires adopt different colours, favourable differentiation.In the cable core gap, fill the glass fibre gasket for packing of heat-resistant fireproof, wrapped polyimide film band on the cable core, the plastic-aluminum mask tape is set on the polyimide film band adds the composite shielding layer that the close net braiding of tin plated wire constitutes, shielding density is more than 90%, strengthen shielding action greatly, improve its interference free performance.The sheath of cable adopts polyfluorinated ethylene plastic, perfluoroethylene-propylene has splendid resistant of high or low temperature (60 ℃～+ 200 ℃), chemical resistance, high flame retardant, resistance to ag(e)ing, so, intelligent instrument heat-resisting and anticorrosive shielded type cable, advantages such as it is good to have high temperature resistant, anti-chemical burn into shield effectiveness, and antijamming capability is strong.
