Composite overhead cable. |
摘要 |
<p>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 (3) having a plurality of axially extending helical grooves (1) formed in an outer surface thereof is positioned within a protective tube (4). Respective optical fibers (2) and/or optical bundles are received in each of the grooves (1). Each of the grooves (1) has a width substantially equal to the outer diameter of the optical fiber (2) 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.</p> |
