摘要（英）：

The invention provides an aluminum-clad nickel-molybdenum alloy steel wire for an overhead conductor and a preparation method thereof. The overhead conductor is composed of a stranded aluminum-clad nickel-molybdenum alloy reinforcing core wire and a wire outer layer, wherein the core wire comprises the following components, in mass percentage, 0.15 to 0.3% of C, 0.1 to 0.2% of Si, 0.2 to 0.3% of Mn, less than or equal to 0.01% of P, less than or equal to 0 .01% of S, 33 to 38% of Ni, 0.5 to 1.2% of Mo, 0.2 to 0.8% of Cr, 0.2 to 0.4% of V, and 0.3 to 0.8% of Be, with the balance of Fe and unavoidable impurities. The aluminum-clad nickel-molybdenum alloy steel wire provided by the invention has excellent toughness and electrical conductivity, and good deformation adaptability. The preparation method of the invention is simple and convenient, and can be widely used in production.
