(Means for solving problems) The present invention was made as a result of intensive studies in view of the above-mentioned circumstances. This is an overhead electric wire with a coating layer of anti-icing paint. However, since the former has an increased surface area and the latter has a bolus structure, the anti-icing paint on the surface must be sufficiently strong to prevent icing from developing and wandering. This makes it possible to suppress vibration phenomena such as gear roping.

Now, if we explain this using Figure 2, it will be as shown in Figure (A)! ,!

In this case, if the icing force is reduced as in the present invention, the maximum icing weight will be small,
It is also possible to suppress vibration effects such as gear lopping.

It is also possible to have a rough surface 3 and 4 coating layers of anti-icing paint on the surface only.

The anti-icing coating used in the present invention is known as, for example, an organopolysiloxane resin paste in which an alkaline metal compound is uniformly dissolved or dispersed in a matrix, and this paste can be applied to the surface of an object. When applied to
Due to the synergistic effect of the anti-icing effects of the silicone resin and the alkali metal compound, it is possible to prevent water from strongly adhering to the surface of objects when it freezes.7 In other words, the IMII of organopolysiloxane resin The glass transition is extremely low due to its low temperature,
For example, even under conditions of minus 30°C, its molecular motion is not zeroed and exhibits extremely low properties, making it difficult to become a target for hydrogen bonding when freezing.

Also, when a water molecule forms a single frozen crystal, the bond angle of the water molecule opens from (HOH=104.3° to 109.5°,
As a result, the volume expands, but since certain gold ions in the film of this anti-icing paint strongly adsorb water molecules around them, even if the surrounding water freezes (109.5 degrees), the surface The water maintains a 104.3' shape and forms an energetic and steric gap between it and the ice on the outside. Not glued.

In addition, in the present invention, the surface area of the electric wire is increased by roughening it, and the coating film of anti-icing paint is made sufficiently thick, but in particular, the surface of the aluminum wire is made porous by anodizing. If I+, the paint penetrates into the inside,
Due to the anchoring effect, it adheres more firmly and forms a fc coating.
