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 is horizontally, with overlapping upper wires in plan view. Overhead power transmission line contains supports (1) and wires mounted on them (3) located on supports vertically relative to each other, and pair of lower wires (4 and 5), arranged horizontally relative to each other and with overlapping L of all upstream wires in plan view, where in middle of separate bay between pair of lower wires (4 and 5) there are two independent bridges (8 and 9) with current-conducting, at least, their surfaces; one bridge (8) with its one end is fixed (10) on one of wires of said pair (4) and galvanically connected to wire, by its second end of this bridge fixed (10) on second paired wire and galvanically disconnected with it by means of dielectric insert 11 located directly in this wire; second bridge (9) fixed in reverse order relative to first one.EFFECT: invention solves task of improving electrical safety of overhead transmission line.1 cl, 2 dwg |
