Abstract

The invention discloses a novel high-strength heat-resistant aluminium-alloy conductor. According to the invention, commercial-purity aluminium is used as a raw material, and traces of boron, antimony, manganese, copper and zirconium elements are added at 800+/-10 DEG C. the novel high-strength heat-resistant aluminium-alloy conductor comprises components of, by weight, 0.01-0.30% of boron, 0.05-0.60% of antimony, 0.02-0.80% of manganese, 0.05-2.30% of copper, 0.05-0.90% of zirconium and the balance pure aluminium and unavoidable impurities. The novel high-strength heat-resistant aluminium-alloy conductor is manufactured by a conventional alloy smelting technology. The prepared aluminium-alloy conductor has high strength, good heat resistance and excellent conductivity. Comprehensive performance of the conductor is raised effectively. The aluminium-alloy conductor can be widely applied in national electric transmission lines, especially a long-span long-distance transmission and transformation project.

Description

technical field [0001] The invention relates to a novel high-strength heat-resistant aluminum alloy wire, which belongs to the technical field of aluminum alloy wires. Background technique [0002] With the rapid development of my country's national economy, the construction of the electric power industry presents a trend of rapid development. The large-span transmission lines under construction have been developed and extended toward high voltage, large capacity, and long-distance. Only using traditional aluminum conductors can no longer meet the strategic deployment of "west-to-east power transmission, north-south mutual supply, and national networking". The need for large spanning transmission lines. There is an urgent need to research and develop new aluminum alloy wires with high strength, heat resistance and medium conductivity. [0003] In actual production, the heat resistance, tensile strength and electrical conductivity of aluminum wires are a pair of contradicti...
