ABSTRACT:
An overhead cable including a plurality of element wires stranded to form a naked stranded cable, which has a cross-sectional shape of an equilateral polygon inscribed in a circle having a diameter of 18.2 mm to 38.4 mm as a fundamental cross-sectional shape, in which two sides of this equilateral polygon that are located at positions farthest from each other are outwardly projected, has two flat-plate-shaped projections corresponding to the two sides, wherein the number of angles of the equilateral polygon is set depending to the diameter of the circle.
