Description
Technical field
The utility model relates to field of cable technology, particularly relates to a kind of steel-aluminum wire flat cable.
Background technology
Along with the development of advancing by leaps and bounds of power industry, the demand of cable just increases progressively with the annual growth of 10 ~ 15%.Wire mainly copper and the aluminium that present wires and cables industry is used, because copper valency is soaring at a high speed, in order to reduce producing cost, world's wires and cables industry proposes using aluminium for the method for copper as electric wire wire.At present, China's aluminium production capacity surplus, meanwhile, the breach of copper material is large needs import, in order to change the dependence to copper material, makes full use of Domestic Resources, ensures that the key of power industry sustainable development widelys popularize the wire of aluminium as electric wire.In cable industry, aluminium replaces the ideal material of copper, but fine aluminium wire exists again some shortcomings as bad mechanical strength, easily creep, easily overload heating etc.
The wire diameter of conventional aluminium leader cable is comparatively large, and when being subject to external world power, its defensive ability/resistance ability is poor, easily causes puncturing, and Heavy Weight, installation cost is quite high, in addition poor corrosion resistance, and useful life is not long.This common cable structure, cannot run for a long time in adverse circumstances, and processing is more complicated and difficult.Under normal circumstances, existing cable can meet the demands, if but cable be used in adverse circumstances and require in higher environment, then can not meet instructions for use to cable security.
Utility model content
For solving in background technology the technical problem existed, the utility model proposes a kind of steel-aluminum wire flat cable, it conduct electricity very well, stretch-proof, high temperature resistant, advantages of good shielding performance.
A kind of steel-aluminum wire flat cable that the utility model proposes, comprising: multiple conducting wires and the restrictive coating being extruded in wire outside, and the axis being parallel of multiple conducting wires arranges and keeps at grade, by jacket layer material interval between adjacent wires; Wire comprises the steel core being positioned at middle part, the conductor layer being coated on steel core outside, is coated on the insulating barrier of conductor layer outside, is coated on the metallo-plastic composite bed of insulating barrier outside, steel core forms by many steel wires are stranded, every root steel wire outside is coated with aluminium lamination, conductor layer forms by many aluminium conductors are stranded, is evenly provided with the through hole extended along cable axis in restrictive coating.
Preferably, the cross section of steel core is circular.
Preferably, the distance between arbitrary neighborhood two wires is equal.
Preferably, restrictive coating adopts tear-proof silastic material to make.
Preferably, refrigerating gas can be passed in through hole.
Preferably, metallo-plastic composite bed employing double-sided metal plastics composite band is wrapped to be formed, and be metal level in the middle of it, both sides are plastic layer.
In the utility model, the steel-aluminum wire pattern flat cable proposed, comprise multiple conducting wires and the restrictive coating being extruded in wire outside, the axis being parallel of multiple conducting wires arranges and keeps at grade, by jacket layer material interval between adjacent wires, be provided with aluminium Baogang core in wire, in restrictive coating, be provided with multiple through hole.With the above-mentioned cable arranging design, on the one hand, at the outside metallized aluminum conductor layer of steel core, while ensure that the electric conductivity of conductor, improve the stretch-resistance of conductor, on the other hand, the insulating barrier outside clad metal plastics composite bed of every root wire, while the total weight not affecting cable, improve the capability of electromagnetic shielding of cable, again on the one hand, in restrictive coating, establish through hole, be convenient to the heat produced in the work of heat radiation cable.
Accompanying drawing explanation
