Problems solved by technology

All-aluminum alloy stranded wire has also been used to a certain extent in recent years, but due to its low conductivity (53.5%IACS), it is still difficult to popularize and apply it in large quantities.
59% IACS medium-strength aluminum alloy conductors have also been developed, but most of them are aluminum-magnesium-silicon-based, heat-treated, and the production process is complicated, which does not meet the requirements of the national energy-saving and emission-reduction policies.

Abstract

The invention relates to a method for manufacturing a non-aging aluminum alloy wire, in particular to a method for manufacturing an aluminum alloy wire used in an overhead power transmission line, and a product produced by the method. The non-aging aluminum alloy wire of the present invention includes the following ingredients in weight percentage: Mg 0.08-0.20%, Fe 0.10-0.25%, Cu0.05-0.18%, the sum of Ti, V, Mn, Cr elements≤0.01%, and the rest is Aluminum liquid. The conductivity of the aluminum alloy wire produced by the above alloy formula can reach 59%IACS, and the strength can reach 240-255MPa. The aluminum alloy wire stranded with this single wire has high conductivity, low resistance loss, good arc sag characteristics, and no hysteresis. Loss, overload performance and other characteristics.

Description

technical field [0001] The invention relates to a method for manufacturing a non-aging aluminum alloy wire, in particular to a method for manufacturing an aluminum alloy wire used in an overhead power transmission line, and a product produced by the method. Background technique [0002] In the process of applying aluminum alloy in China, steel-cored high-strength aluminum alloy stranded wire is generally used, and it is applied in large-span and heavy ice areas. All-aluminum alloy stranded wire has also been used to a certain extent in recent years, but due to its low conductivity (53.5%IACS), it is still difficult to popularize and apply it in large quantities. 59% IACS medium-strength aluminum alloy conductors have also been developed, but most of them are aluminum-magnesium-silicon-based, heat-treated, and the production process is complicated, which does not meet the requirements of the national energy-saving and emission-reduction policy.
