摘要： An overhead cable provided with a plurality of segment strands of a sector-shaped cross-section twisted at the outermost layer and having grooves of a substantially arc-shaped cross-section at the surface at the adjoining portions of the segment strands. Also, a low sag, low wind load cable provided with tension-bearing cores comprised of strands having a linear expansion coefficient of -6.times.10.sup.-6 to 6.times.10.sup.-6 /.degree.C. and an elastic modulus of 100 to 600 PGa and with a plurality of sector-shaped cross-section segment strands twisted around the outermost circumference of the cable including the tension-bearing cores comprised of a super-high-heat resisting aluminum alloy or extra-high heat resisting aluminum alloy, grooves of a substantially arc-shaped cross-section being provided at the surface at adjoining portions of the twisted segment strands. This enables the wind load to be reduced. Further, a low wind load cable can be easily fabricated at a low cost. In addition, by using invar strands for the cores and using segment strands of a super-high heat resisting aluminum alloy or extra-high heat resisting aluminum alloy at the outermost layer, the sag at high temperatures can be greatly suppressed. Accordingly, even the amount of the sideways swinging caused when the overhead cable is struck by a strong wind from the lateral direction can be greatly suppressed together with the low wind load construction.

摘要： An overhead cable includes an outermost surface formed by twisting together a plurality of segment strands. A plurality of spiral grooves form recesses having substantially rectangular cross-sections and are provided at intervals in a circumferential direction of either the outer surface of the segment strands or the outer surface regions of boundary portions where twisted segment strands adjoin each other. Thin segment strands and at least one thick segment strand form the outermost layer. A recessed portion is provided at one side surface among two surfaces of the segment strands forming the outermost layer, a projecting portion is provided at the other side surface, and the strands are twisted together so that the recessed portions and the projecting portions mate. The recessed and projecting portions formed at the two side surfaces of the segment strands mate with each other to form recess-projection mating portions, and the lengths of the contact of the recessed and projecting surfaces at the recess-projection mating portions is configured to be no more than 10% of the length of the recess-projection mating portions.

The outermost layer is formed by twisting together a plurality of adjoining segment strands. A spiral groove is provided in the longitudinal direction along the boundary portion of the outer circumferential surface of each adjoining segment strand. Along the contour of a cross-section of this outermost layer, each groove comprises an arc-shaped curve having a radius R centered around a vertex of a regular polygon. Each part between adjoining grooves comprises an arc-shaped curve which is concave with respect to a straight line connecting adjoining of a regular polygon, intersecting the arc-shaped curve with radius R.
