The low wind noise electric wire 1 has a structure in which ridges 2 are formed at symmetrical positions on the outer peripheral surface. Since the ridge 2 is formed of the outermost strand, it has a spiral shape in the longitudinal direction. The ridges 2 disturb the flow of the air blown to the electric wires 1 to reduce wind noise.

電が発生することはない。When the ridges are formed as described above, the ridges and ridges protrude from the outer peripheral surface of the electric wire, and the respective tops are connected by a substantially circular envelope, so that the potential gradient near the ridges is reduced. And corona discharge hardly occurs. Since the peak has a gently raised shape, corona discharge does not occur from the peak.

FIG. 1 shows an embodiment of the present invention. In this low wind noise electric wire 1, a ridge 2 for preventing wind noise is formed at a symmetrical position on the outer peripheral surface, and a ridge 3 gently rising at an intermediate position between the ridges 2 on the outer peripheral surface is formed.

にくいので、突条２より若干高くしても差し支えない。The ridges 2 and the ridges 3 can be formed by changing the cross-sectional shape of the outermost strand. It is desirable that the height of the ridges 3 be equal to the height of the ridges 2 and that the tops of the ridges 3 be connected by a substantially circular envelope A. The peak 3 is a gentle swell, and corona discharge is unlikely to occur, so that it may be slightly higher than the ridge 2.

ナ放電の発生しにくい電線を得ることができる。As described above, according to the present invention, a ridge for preventing wind noise and a gently rising ridge are formed on the outer peripheral surface, so that low wind noise and corona discharge can be obtained. It is possible to obtain an electric wire that is hardly generated.
