The invention discloses a waste cable conductor regeneration method. The waste cable conductor regeneration method comprises the five steps of performing conductor prefabrication, smelting furnace prefabrication, conductor smelting, conductor modification, alloy surface treatment and the like. The method is simple in preparation method, easy to master, low in production cost, and capable of effectively improving repeated utilization rate of the cable recycled conductors, and effectively improving the guiding performance, the corrosion resistance performance and high temperature resistance performance of an aluminum-based conductor as well as effectively improving the structural strength, the flexibility, the tensile strength, the anti-fatigue performance and the machining performance of the aluminum-based conductor, thereby effectively improving the conductive performance stability and reliability of the cable product and lowering production and preparation costs of the cable product.
