A snow melting member for use on a power transmission line which can sufficiently melt snow even when the magnetic field created by the current in the power transmission line is relatively small. The snow melting member is composed of metals or metal oxides and has an annular, tubular or helical configuration for surrounding the outer periphery of the power transmission line. The snow melting member is provided with the dimensions and electromagnetic properties defined by the following formulas: Hx BH >/= 40,000; and 0.7</= t0(BH/ rho . H)<1/2></= 7. By winding an iron alloy wire containing 1 to 15% by weight of aluminum around the power transmission line, or by attaching an iron alloy ring onto the power transmission line, heat is generated even when a relatively small amount of current flows through the power transmission line, thereby melting snow or ice sticking to the power transmission line. <IMAGE> |
