<p>PURPOSE:To make is possible to carry out the work without using large-scale construction machinery and without requiring a high strength for steel towers when installing accompanied wires to the conductor at the ground side of a multiple-conductor power transmission line. CONSTITUTION:When installing a conductive accompanied wire by giving a sag to the bottom of two conductors 12A almost at the central part at the ground side among a plurality of conductors of multiple-conductor power transmission line, a short conductor 14A is utilized as the accompanied wire. One end of this short conductor 14A is fixed, its middle portion is supported by an intermediate auxiliary metal part 20, its other end side is adjusted and fixed to obtain a predetermined sag, and then an intermediate auxiliary metal part 20 is removed. By using the short conductor 14A as the accompanied wire, it becomes unnecessary to transport a long conductor as accompanied wire to the site and the layout becomes much easier and also a predetermined sag can be obtained with a small tension since the accompanied wire is held by the intermediate auxiliary metal part 20 during installation for accompanying.</p> |
