ものである。(Means for Solving the Problems) The present invention provides a low wind noise electric wire that solves the above-mentioned problems.The present invention has a structure in which a plurality of spiral strands, at least two of which are arranged in parallel, are arranged so that their ends are adjacent to each other. In a low wind noise electric wire that is wound around the outer circumference of the electric wire in sequence, the spiral wires are arranged in parallel so that their ends become sequentially longer, and the ends of the spiral wires having the longest ends are adjacent to each other. It is characterized by being wrapped around the outer circumference of the electric wire.

る。(Function) As described above, multiple spiral wires arranged side by side so that their ends become longer are wound around the outer periphery of the electric wire so that the ends of the spiral wires with the longest ends are adjacent to each other. By doing so, the ends of the outer spiral strands do not protrude, and therefore corona can be prevented from being generated from the ends of the outer spiral strands.
（実施例）
以下、本考案の一実施例を第１図を参照して詳

発生するのを防止できる。 The low wind noise electric wire of the present invention is the same as the conventional one in that a plurality of spiral wires 1 arranged in parallel are sequentially wound around the outer circumference of the electric wire 2 so that their ends are adjacent to each other. The strands 1 are arranged in parallel so that their ends become sequentially longer, and the spiral strands 11 having the longest ends are characterized in that the ends of the spiral strands 11 are adjacent to each other and wound around the outer periphery of the wire. That is, the end of the inner spiral wire 11 of the two spiral wires 1 arranged in parallel is made longer than the end of the outer spiral wire 12 by L, so that the inner spiral wires 11 with longer ends are separated from each other. It is wrapped around the outer circumference of the wire with the ends adjacent to each other. Therefore, the end of the spiral wire 12 is shorter than the end of the spiral wire 11 by L. Therefore, the end of the outer spiral wire 12 does not protrude, and
It is possible to prevent corona from being generated from the ends of the outer spiral strands 12.

のである。 In the above embodiment, two spiral wires are arranged in parallel, but three spiral wires may be arranged in parallel. In this case, the plurality of spiral wires are arranged in parallel so that their ends become sequentially longer, and the ends of the spiral wires with the longest ends are placed adjacent to each other and wound around the outer periphery of the wire. be.
