ABSTRACT:
A snow-melting apparatus of an electromagnetic induction heating type, comprises: a high frequency power source; a pair of conductive cables wound in at least one turn around a segment of each rail and through through-holes which are formed through side walls of the rail, the segment of the rail being defined between two through-holes; and a lead wire interconnecting the power source and the conductive cable, for supplying current from the power source to the conductive cable, thereby heating the rail by the flow of electromagnetic ally induced current in the rail segment.
