The present invention realizes an increase of the capacity of a power transmission wire without replacing an already strung aerial power transmission wire. For this purpose, a braided heat conducting wire heat dissipating belt (1) treated to blacken its surface so that a surface heat dissipation rate becomes 0.7 or more or a surface-blackened heat dissipating spiral rod is wound around an outer circumference of an already strung aerial line (2) or jumper (8) so as to increase the heat dissipation effect of the surface of the aerial line (2). Heat dissipation enables the capacity of a permissible power supply of the already existing aerial line (2) to be increased. Further, the braided heat conducting wire heat dissipating belt (1) shares the transmission function and lowers the wind noise.
