Description

Technical field [0001] The invention belongs to the technical field of aluminum alloys, and particularly relates to a non-heat-treated heat-resistant aluminum alloy monofilament. Background technique [0002] With the rapid development of my country's economic construction and the increasing demand for electricity year by year, how to make full use of existing line corridors and line facilities to transmit as much electricity as possible, reduce line losses, and improve transmission efficiency have become issues that must be considered by the power operation department. [0003] At present, steel core aluminum stranded wire is commonly used in my country's high voltage, ultra high voltage and UHV overhead transmission lines. The production and application technology of this type of steel core aluminum stranded wire is basically mature, but its transmission line has high loss, poor corrosion resistance and low current carrying capacity. . The use of all aluminum alloy conductors (AA...
