状である。However, such preventive measures are not perfect, and there is a disadvantage that power failure due to disconnection or breakage, electric leakage, damage to houses or the like due to falling snow, etc. often occur. Generally, it is widely known that electric wires generate heat when electricity flows. Due to this heat, the surface of the electric wire usually rises up to about 20 ° C. above the ambient temperature. In winter, due to this heat, the wire surface becomes around 0 ° C, and the snow melts at the beginning of snowfall and when there is little snowfall, but when the snowfall falls for a long time and in large quantities, it melts on the melting snow on the wire surface, It is usual that snow accretion gradually increases, and no measures have been taken to prevent this.
