Abstract
Cold drawn carbon steel wire, more particularly stranded galvanized wire for use in overhead power transmission lines, is heat treated in the untensioned state for a period of at least one hour at a temperature in the range 150.degree. C.-200.degree. C. The preferred temperature is about 175.degree. C. The treated wire has a reduced susceptibility to permanent elongation under tensile stress. ACSR conductors incorporating such wire as the steel reinforcement have a greatly reduced sag under heavy ice loading.
