Abstract
An improved composite overhead stranded conductor obtained by providing an optical fiber cable in an overhead power line formed by stranding a plurality of conductors, or in an overhead earth wire which is extended in parallel with such an overhead power line. A spacer having a plurality of axially extending helical grooves formed in an outer surface thereof is positioned within a protective tube. Respective optical fibers and/or optical bundles are received in each of the grooves. Each of the grooves has a width substantially equal to the outer diameter of the optical fiber and/or the optical bundles received therein so that movement of the optical fibers and/or the optical bundles in the grooves in the circumferential direction of the spacer is restricted.
