Abstract
The utility model provides a steel core copper clad aluminum stranded wire, comprising a steel core layer formed by stranding a plurality of steel wires, and an electric lead wire layer formed by stranding a plurality of copper clad aluminum wires. The electric lead wire layer is stranded on the steel core layer. The copper clad aluminum wire comprises an aluminum wire and a copper layer which is coated on the surface of the aluminum wire, and the shape of the cross sections of the steel core and the copper clad aluminum wire is round. The steel core copper clad aluminum stranded wire has the compound characteristics of good electric conductivity of the steel core copper stranded wire and light specific gravity of the steel core aluminum stranded wire, a great amount of scarce copper resource is saved, the line electric energy loss is reduced, the structure is simple, the comprehensive breaking force is strong and the construction is convenient.
Description
[technical field]
The utility model relates to a kind of electric wire, particularly a kind of steel core copper cover aluminum twisted wire.
[background technology]
Overhead transmission line generally adopts the steel reinforced aluminium conductor product at present, this series products possesses lightweight characteristics, being suitable for the built on stilts of large span lays, but it exists the relatively poor problem of conductance simultaneously, conductance only is 61% of an international standard copper, therefore electric energy loss is quite big, problems such as when cable is set up in city suburbs and rural area, can causing difficult design, increase shaft tower quantity, expense increases, nargin is not enough; And the steel core copper stranded conductor, though the conductance height, owing to self than great, when setting up cable, cause unit mass big, sag is big, span is little, increases problems such as cost, does not lay so also be suitable for the built on stilts of large span.
[utility model content]
The technical problems to be solved in the utility model is to provide a kind of steel core copper cover aluminum twisted wire, and it can have the composite attribute of steel core copper stranded conductor favorable conductive rate and steel reinforced aluminium conductor light specific gravity simultaneously.
The utility model is achieved in that
A kind of steel core copper cover aluminum of the utility model twisted wire, the steel core layer that comprises the stranded formation of a plurality of steel wires, it also comprises the line conductive layer of the stranded formation of a plurality of copper-clad aluminum conductors, and described line conductive layer strand is on described steel core layer, and described copper-clad aluminum conductor comprises aluminum steel and covers the copper layer on aluminum steel surface.
Further, the cross sectional shape of described steel core and described copper-clad aluminum conductor is circular.
Advantage of the present utility model is:
The utility model has adopted steel core and copper-clad aluminum conductor stranded as cable core, has possessed the composite attribute of steel core copper stranded conductor favorable conductive rate and steel reinforced aluminium conductor light specific gravity; Steel core copper cover aluminum twisted wire has been saved a large amount of rare copper resources with more excellent electric conductivity and low-gravity composite attribute, reduced the circuit electric energy loss, simultaneously simple in structure, comprehensive breaking strength is strong, be convenient to construction, have remarkable social benefit and economic benefit, when transmission line set up use, the conductance of copper-clad aluminum conductor can reach about 65%IACS, and density only is about 37% of copper, and electric energy loss is little, and creep compliance is less, has reduced the sag amount of electric wire.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is an end face structure schematic diagram of the present utility model.
[embodiment]
Consult Fig. 1, embodiment of the present utility model is elaborated.
As shown in Figure 1, the utility model embodiment comprises the line conductive layer 2 of the steel core layer 1 of a plurality of steel wire 11 stranded formations, a plurality of copper-clad aluminum conductor 21 stranded formations, and described line conductive layer 2 strands are on described steel core layer 1.Described steel core layer 1 is one or more steel wire, 11 stranded forming, and present embodiment is 7 steel wires, 11 stranded forming.Described line conductive layer 2 is made of a plurality of copper-clad aluminum conductors 21, and described copper-clad aluminum conductor 21 is to constitute at aluminum steel surface coverage last layer copper, and copper-clad aluminum conductor 21 is to adopt advanced clad welded manufacturing technology, high-quality copper strips is coated on one heart the outer surface of aluminium core.The conduction single line of line conductive layer 2 is many copper cover aluminum lines 21 stranded forming, with described steel core 1 and the cable core of the circular stranded conductor of copper cover aluminum single line 21 stranded formation as cable.Because high-frequency signal has the characteristics of " skin effect ", so copper-clad aluminum conductor 21 has the electric conductivity identical with pure copper wire when transmitting high-frequency signal (greater than 5MHz), and copper-clad aluminum conductor 21 possesses the conductivity of copper and the little composite attribute of density of aluminium simultaneously.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented according to this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
Claims (2)
