FIELD: electricity.SUBSTANCE: overhead power transmission line comprises supports 1, on which by means of fixtures with insulators 2, there are wires 3 suspended along the vertical line on the supports. The lower wire is made as split into two wires - 4 and 5, which by means of rods with insulators 6 are fixed on cross beams 7, with coverage L of the above wires in the plan. In each span both wires 4 and 5 are connected galvanically to each other by at least one electroconductive link 8 in the form of a wire section, connected to the wires 4 and 5 by means of clamps 9. At the same time the total electric conductivity of both halves of the split lower wire (wires 4 and 5), and also electroconductivity of the link 8, are equal to the design electroconductivity of the lower non-split wire.EFFECT: increased electric safety of an overhead power transmission line.2 dwg |
