摘要： A method of installing an optical cable in an overhead power transmission line which comprises supporting an optical cable (1), which has an overall protective sheath of electrically insulating material, in long lengths between towers employed to support at least one electric power transmission line (2) which is on load and, after the optical cable (1) has been so installed and while the overhead electric power transmission line is on load, providing on or in the supported optical cable at least one longitudinally continuous path (11) which extends throughout substantially the whole length of the supported optical cable and which is sufficiently electrically conductive to carry along the cable (1) any currents that may be capacitively induced. The method enables a cable that will not be subject to dry-band arcing to be installed without danger to personnel during installation.
