Abstract
Incorporation of optical fibres in an electrical overhead power line which is constructed of several layers of wires with the same diameter so that the cable is not thicker and heavier than a comparable cable with the same linear resistance, is carried out principally in such a way that the optical fibre bundle 6 is placed in a tube 5 of special steel, which tube is placed in the cable instead of one wire 1 in a layer of wires 3 positioned under the outermost layer 4. An economic incorporation is where a tube of synthetic material is used instead of the tube of special steel and where the spare space beside the bundle of optical fibres 6 is filled with a non- compressible paste-like substance 7. <IMAGE>
