Abstract (en)

A heat-generative electric wire (1) comprising a Ni-Fe alloy wire member (3) which contains 45 to 80% by weight of Ni with the remaining portion being substantially Fe and which is wound on or stranded with the outermost layer of an overhead electric wire (2) exhibits adequate heat generation at low power transmission to melt adhered snow or ice and permits high power transmission without excessive heat generation.
