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.
