Abstract
The utility model relates to an aluminum-clad round steel core allotype wire, which comprises a core wire and an outsourcing allotype aluminum coating, wherein the wire core is a steel wire whose cross section is round, the shape of the cross section of the allotype wire is a fan shape and changed fan shapes which are a C-shaped fan shape, a Z-shaped fan shape and a broken line fan shape based on a fan shape, and the aluminum coating is electrical aluminum, pure aluminum, rare-earth aluminum or alloy aluminum. The utility model is used to make stranded wires of overhead transmission lines, overhead grounding lines and optical fiber composite overhead ground wires, compared with round single line stranded wires with same outer diameter, the utility model has the advantages that the structure of the stranded wires which are made by the utility model is compact, the outer surface is smooth, the tightness of the structure is equal or greater than 95 percent, the wind load and the ice load are small, the tensile strength is high, the current carrying capacity is big, the utility model resists corrosion, and the service life is long.
Description
Affiliated technical field
The utility model relates to a kind of aluminium Baogang single line of circular steel core, the aluminium that can bear big tensile strength and the improve conductive capability steel core single line that takes all of, particularly with circular steel core strengthen, cross section is that the special-shaped line of non-circular aluminium Baogang is the aluminium special-shaped line of steel core that takes all of.
Background technology
At present, the shape of aluminum-cladding stranded wire that is used for overhead power transmission line, overhead ground wire, the Optical Fiber composite overhead Ground Wire of electricity overhead power transmission line is that cross section is circular round single line mostly, all be the line contact between the adjacent single line of twisted wire that these circle single lines are made, between the line of twisted wire and the line and the gap between strand layer and the strand layer is bigger, loosely organized, general structure tightness causes crevice corrosion about 75%, the wind load ice load strengthens, and influences twisted wire useful life.
Summary of the invention
Existing aluminium Baogang circle single line twisted wire gap is big, loose in order to overcome, wind load, ice load is big, current capacity is low etc. deficiency, the utility model provides a kind of aluminium special-shaped line of steel core that takes all of, whole twisted wire compact conformations made from it, structure tightness 〉=95%, wind, ice load are little, the tensile strength height, current capacity is big, long service life.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of aluminium special-shaped line of steel core that takes all of, forms by round steel core and aluminium covering, and it is characterized in that with the cross section being that circular steel wire is to strengthen heart yearn, the special-shaped aluminium covering of outsourcing; The take all of shape of cross section of the special-shaped line of steel core of above-mentioned aluminium is fan-shaped, as long as fan-shaped adjacent radial line is added little circular arc or is varied to various broken lines, just can make its shape of cross section produce multiple variation, fan-shaped such as fan-shaped, the Z-shaped various distortion fan-shaped, the fan-shaped multiple front and back of broken line shape complementarity of C shape, the part of its concaveconvex shape complementation constitutes various tenon structures, because the combination of the tenon structure of these concavo-convex complementations, twisted wire with this identical special-shaped line after stranded in conjunction with tightr, firm, be difficult for loose; The material of above-mentioned aluminium covering is electrician's aluminium, fine aluminium, rare earth aluminium or leads alloy aluminum.
The beneficial effects of the utility model are the various overhead transmission lines that all are twisted into the special-shaped line of this kind in the structure, built on stilts earth connection, Optical Fiber composite overhead Ground Wire, round single line twisted wire ratio with same outer diameter as, the twisted wire compact conformation that the utility model is made, structure tightness 〉=95%, smooth surface, wind load, ice load are little, the tensile strength height, ampacity is big, and is corrosion-resistant, long service life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is that the utility model shape of cross section is the fan-shaped aluminium special-shaped line cross-sectional view of steel core that takes all of.
