<p>PURPOSE:To inexpensively provide a heat wire constituted such as to enable to melt snow on the periphery of a supporting wire for a pole to be supported, such as an electric pole, by continuously feeding a long core member comprising heat pipes and dummy members connected to each other into the twisting center of a twisting wire and forming the twisting layer on the outer periphery of the long core member. CONSTITUTION:Heat pipes 1 and dummy members 2 are continuously connected to each other with an adhesive tape 3, etc., to form a long core member, which is wound on a drum and carried into a wire-twisting machine. When a twisting operation is carried out, the long core member comprising the connected heat pipes 1 and dummy members 2 is taken out as such from the drum and continuously fed, simultaneously twisting a twisting wire 7 on the fed long core member to provide the objective heat wire 10. The heat wire 10 is disposed between an electric pole 11 and an anchor 12 in a tense state to form a supporting wire, and one end of the formed composite heat wire is embedded in the ground to form a heat-collecting section 10a and the other end is used as a heat-releasing section 10b to melt the snow on the periphery of the heat-treating section 10b, thereby cutting the transmission of the sedimentation power of the snow to the supporting wire to prevent the breakage of the supporting wire.</p> |
