Abstract
An anti-bending anti-interference high temperature cable belongs to the technical field of cables. The cable consists of a cable core twisted by insulating wire cores, a shielding layer and an outer jacket outside the cable core and the like, wherein a reinforcing rib is arranged in the middle of the cable core; the cable core in the shielding layer is provided with a polyimide film strip winding layer; the shielding layer is a composite shielding layer formed by adding a tin-plated wire woven dense screen on an Al-plastic shielding strip; and a silicon rubber outer jacket is extruded on the tin-plated wire woven dense screen of the composite shielding layer. The insulating wire cores are formed by extruding and coating a fluorinated ethylene propylene insulating layer on a plurality of tin-plated soft copper wire bundle conductors. The reinforcing rib is formed by extruding and coating the fluorinated ethylene propylene insulating layer on 19 twisted zinc-plated soft steel wires. The anti-bending anti-interference high temperature cable has the advantages of rational and simple structure, easy production and manufacture, low cost, excellent service performance, high temperature resistance, bending resistance, good shielding effect, and strong anti-interference performance and the like and is suitable for electrical system projects in steel, electrical, and petrochemical industries and the like or particular environments.
Description
Technical field
The utility model relates to a kind of structure of cable, belongs to the cable technology field.
Background technology
At present, the high temperature series cable has been used widely in the electrical system engineering of industries such as iron and steel, electric power, petrochemical industry, but along with the complexity of engineering-environment changes, a lot of occasions improve constantly the performance requirement of cable, still can normally move to satisfy under particular surroundings, except that high temperature resistant, as require softness, suitable frequent move, tension, antijamming capability be strong or the like.So, develop a kind of cable that can satisfy above-mentioned requirements, be a urgent task of cable R﹠D institution and production industry.
The utility model content
The purpose of this utility model is exactly for satisfying the needs in market, provide a kind of adaptability strong, the warping strength anti-interference high-temperature cable that serviceability is good.
The purpose of this utility model is to realize like this, warping strength anti-interference high-temperature cable, comprise the cable core and outer screen, the oversheath of cable core that are twisted into by insulated wire cores, the centre that it is characterized in that cable core is provided with a reinforcement, cable core in the screen is provided with polyimide film band lapping layer, described screen is for to weave the composite shielding layer that close net constitutes by adding tin plated wire on the plastic-aluminum mask tape, and the tin plated wire of composite shielding layer weaves the close silicon rubber oversheath that extrudes on the net.
Described insulated wire cores is for to constitute by extruding the perfluoroethylene-propylene insulating barrier on the zinc-plated soft copper wire bundle conductor of multiply.
Described reinforcement is for to constitute by extruding the perfluoroethylene-propylene insulating barrier on 19 strands of stranded galvanized mild steel silks.
The utility model is rational in infrastructure simple, manufactures easily, and cost is low, and serviceability is good.This cable carries out system's improvement and upgrading to its process structure and material on the basis of conventional cable, its conductor adopts the zinc-plated soft copper wire bundle of multiply to close, structurally flexible, and under the condition of high temperature, oxidative phenomena can not take place in conductor.Insulating barrier is a polyfluorinated ethylene plastic, adopts the high temperature extrusion process, guarantees the insulating barrier uniformity, and this material has good high temperature resistant and electrical insulation capability, ageing-resistant.Cable core is placed 19 strands of stranded galvanized mild steel silks that insulating barrier is arranged by stranded the forming of some different colours insulated wire cores in the middle of the cable core, play tension, warping strength effect, and the steel wire insulating barrier also adopts polyfluorinated ethylene plastic.At the outside wrapped polyimide film band of cable core with high temperature resistant character, this material still can keep its good characteristic more than 200 ℃, the shielding of cable adds tin plated wire by the plastic-aluminum mask tape and weaves the composite shielding layer that close net constitutes, shielding density is more than 90%, strengthen shielding action greatly, improve its interference free performance.Oversheath adopts the silicone elastomer protective cover material, and this texture material is soft and high temperature resistant.Advantage such as that this cable has is high temperature resistant, warping strength, shield effectiveness is good, and antijamming capability is strong.Use through test, be subjected to the high evaluation of Subscriber Unit, be applicable to that the electrical system engineering under industry such as iron and steel, electric power, petrochemical industry or the particular surroundings is used.
Description of drawings
Fig. 1 is an architecture schematic diagram of the present utility model;
Among the figure: the zinc-plated soft copper wire bundle conductor of 1 multiply, 2 perfluoroethylene-propylene insulating barriers, 3 stranded galvanized mild steel silks, 4 perfluoroethylene-propylene insulating barriers, 5 polyimide film band lapping layers, 6 plastic-aluminum mask tapes, 7 tin plated wires weave close net, 8 silicon rubber oversheaths.
Embodiment
Constitute insulated wire cores by extruding perfluoroethylene-propylene insulating barrier 2 on the zinc-plated soft copper wire bundle conductor 1 of multiply, can need to be provided with different colours on the insulated wire cores.Constitute reinforcement by extruding perfluoroethylene-propylene insulating barrier 4 on 19 strands of stranded galvanized mild steel silks 3.Insulated wire cores and a reinforcement by some different colours are twisted into cable core, and reinforcement is placed at the centre of cable core.Wrapped polyimide film band lapping layer 5 on cable core, in polyimide film band lapping layer 5 wrapped one deck plastic-aluminum mask tapes 6, tin plated wire weaves close net 7, tin plated wire weaves on the close net 7 and extrudes silicon rubber oversheath 8 being provided with on the plastic-aluminum mask tape 6.
