PROBLEM TO BE SOLVED: To provide a steel tower for supporting an electric wire, which can inhibit a short circuit accident from occurring between the electric wires due to snakes ascending to the tower, and inhibit a ground fault accident from occurring between the electric wire and a ground surface.SOLUTION: A snake actively moves at a high temperature in ordinary cases. The utilization of this habit makes the application of paint with high thermal absorptivity or the affixation of a sheet performed on a surface of a lower part of a steel tower 1, and makes the application of paint with high thermal shielding performance or the affixation of the sheet performed on a surface of an upper part of the steel tower 1. The ascent of the snake to the tower is prevented by rapidly decreasing the sensible temperature of the snake when the snake ascends to the tower. |
