Claims (2)

1. Линия электропередачи, включающая по меньшей мере одну опору, по меньшей мере один изолированный провод, по меньшей мере один изолятор указанного провода от указанной опоры, крепежный элемент, фиксирующий указанный силовой провод на указанном изоляторе, а также средства защиты указанного изолятора от грозовых перенапряжений, отличающаяся тем, что указанные средства защиты выполнены в виде по меньшей мере одного отверстия в изоляции провода, причем это отверстие удалено от указанного крепежного элемента на расстояние, определяемое из выражения
0,06 U0,75 - h < l < 0,5 U0,75 - h,
где l - расстояние от указанного отверстия до указанного крепежного элемента, м;
h - длина пути перекрытия защищаемого изолятора, м;
U - номинальное напряжение линии, кВ.
1. A power line comprising at least one support, at least one insulated wire, at least one insulator of the specified wire from the specified support, a fastener fixing the specified power wire to the specified insulator, and also means for protecting the specified insulator against lightning overvoltages characterized in that the said means of protection are made in the form of at least one hole in the insulation of the wire, and this hole is removed from the specified fastener by a distance determined from expressions
0.06 U 0.75 - h <l <0.5 U 0.75 - h,
where l is the distance from the specified hole to the specified fastener, m;
h is the length of the overlapping path of the insulator to be protected, m;
U is the nominal line voltage, kV.
2. Линия электропередачи по п. 1, отличающаяся тем, что в указанном по меньшей мере, одном отверстии в изоляции провода установлен прокалывающий зажим. 2. A power line according to claim 1, characterized in that a piercing clip is installed in the at least one hole in the wire insulation.
