Abstract
The utility model provides a non-circular steel-core reinforced aluminium-cladding steel wire, consisting of a steel core wire (1) and an aluminium-cladding layer (2); the cross-section shape of the steel core wire is sector, regular polygon or rectangular; the cross-section shape of the aluminium-cladding steel wire can be identical to or different from that of the steel core wire (1). The material of the aluminium-cladding layer is electrical aluminium, pure aluminum, rare-earth aluminium or alumina. The non-circular steel-core reinforced aluminium-cladding steel wire is used for the strand wires of overhead transmission wire, overhead ground wire and optical fiber composite overhead ground wire and has the advantages of compact structure of the strand wires which are all made of the non-circular steel-core reinforced aluminium-cladding steel wire, structural compactness that is not less than 95%, high tensile strength, large loading current, and corrosion resistance.
Description
Affiliated technical field
The utility model relates to that a kind of to have the aluminium Baogang single line, particularly steel core that bear big tensile strength and conductive capability be that non-circular aluminium Baogang molded lines is that non-circular steel core strengthens aluminium Baogang molded lines.
Background technology
At present, the power line, overhead ground wire, the Optical Fiber composite overhead Ground Wire that are used for electricity overhead power transmission line, with aluminum-cladding stranded wire be that cross section is circular aluminium Baogang core single line, all the line contact between adjacent single line after these single lines are stranded, between twisted wire and the gap of strand interlayer is bigger, the structure tightness is lower, generally about 75%, causes crevice corrosion and influences twisted wire useful life.
Summary of the invention
In order to overcome existing cross section is that the twisted wire pore volume made of the aluminium Baogang single line of circular concentric is big, the structure tightness is low, poor corrosion resistance, the deficiency that useful life is short, the utility model provides a kind of non-circular steel core aluminium Baogang molded lines, make its power overhead network of making, overhead ground wire, Optical Fiber composite overhead Ground Wire compact conformation, structure tightness 〉=95%, the tensile strength height, loaded current is big, corrosion-resistant, long service life.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of non-circular steel core strengthens aluminium Baogang molded lines, is made up of steel core and aluminium covering, and the shape of cross section that it is characterized in that the steel core heart yearn is fan-shaped, regular polygon or rectangle; The shape of cross section of above-mentioned non-circular steel core aluminium Baogang molded lines is identical or inequality with steel core heart yearn shape of cross section; The material of above-mentioned conductive aluminum covering is electrician's aluminium, fine aluminium, rare earth aluminium or aluminium alloy.
The beneficial effects of the utility model are twisted wire compact conformations of all making with it, the structure tightness can 〉=95%, than the tensile strength height of the common garden of the whole usefulness of same diameter steel core wire twisted wire, loaded current is big, and is corrosion-resistant, long service life.
