帯においては、その防止策が必要となる。2. Description of the Related Art Snow accretion on overhead power lines is due to a tower collapse accident,
Otherwise, it may cause accidents such as the destruction of houses and vinyl structures such as vinyl houses due to snowfall. Therefore, it is necessary to take preventive measures in snowy areas.

によりその磁性体中に発生する鉄損の発熱で着雪を防止
するとともに、付着した雪を溶かす方法がある。As measures for preventing snow from accumulating on electric wires, for example,
A magnetic material was attached to the outer circumference of the wire in the direction of the line or at a right angle to the line to prevent snow accretion as well as to prevent snow from accumulating due to iron loss generated in the magnetic material due to changes in the magnetic field lines caused by energization of the transmission line There is a way to melt the snow.

面の温度が上昇する原理は、以下のとおりである。In the snow-diffusing power transmission line according to the first aspect of the invention, the exterior of the overhead power transmission line is coated with paint. Therefore, the surface of the overhead power transmission line becomes smooth, and it is possible to prevent the adhesion of ice and snow. Further, in the paint coated on this overhead power transmission line, one particle selected from ZrO 2 and ZrC is dispersed. Therefore, the temperature of the surface of the overhead power transmission line rises, and the adhesion of ice and snow can be prevented.
The principle of increasing the temperature of the surface of the overhead power transmission line by the particles of ZrO 2 and ZrC is as follows.
