FIELD: electrical engineering.SUBSTANCE: invention relates to electrical engineering and can be used on overhead transmission lines with location on supports of upper vertical wires, and pair of lower-horizontally, with overlapping upper wires in plan. Overhead power transmission line comprises supports 1, on which by means of hooks with insulators (2) wires (3), which are located on supports vertically relative to each other. Below said wires (3) are mounted wires (4 and 5) - through insulators (6) on horizontal cross-arms (7). Lower wires (4 and 5) are interconnected in spans by at least one jumper (8), having electroconductive at least of its surface; one end of bridge is connected galvanically to one of said pair of wires, and between second end of jumper and second paired wire there is a dielectric insert (9).EFFECT: invention solves task of improving electrical safety of overhead transmission line.1 cl, 2 dwg |
