摘要： The present disclosure relates to the technical field of conducting wires. Provided are an aluminum alloy wire and a preparation method therefor and a use thereof. The aluminum alloy wire is prepared by means of specific raw materials and according to specific contents, which can effectively improve the tensile strength of a single aluminum alloy wire while ensuring the electric conductivity thereof. The tensile strength and other performances of the single aluminum alloy wire can further be improved in combination with the specific preparation method of the present disclosure. The aluminum alloy wire is used for machining a conducting wire, which can improve the overall pull weight ratio of the conducting wire, reduce the sag of the conducting wire, and greatly reduce the investment cost of a pole tower, thereby providing a new conducting wire selection for an energy-saving overhead conducting wire.
