In the overhead power transmission line obtained in this way, a black coating with excellent hydrophilic properties containing metallic molybdenum is formed on the adhered portions of the stranded wires by the reaction between the acidic ammonium fluoride aqueous solution containing the molybdenum salt and aluminum. As a result, rain does not adhere to the surface of the stranded wires in the form of water droplets, and noise caused by corona discharge is significantly reduced. In addition, since the surface is covered with a matte black film, it blends into the surrounding environment without disturbing the harmony.
