Abstract
A cable having an electrically conducting wire with a cross sectional shape defined by a simple closed curve having from three to eight concave portions separated by an equal number of convex portions. The simple closed curve has no point where the radius of curvature is less than one-sixth (⅙) of an overall radius of the wire and no point where adjacent curves or lines intersect at an angle. The alternating concave and convex portions of the cable's cross-sectional shape may have substantially the same curvature. The cross-sectional shape of the cable avoids sharp angles and fight curves.
