Abstract

Replacing traditional steel-cored aluminum stranded conductors with heat-resistant conductors is a key method for upgrading and increasing the capacity of old transmission lines, but heat-resistant conductors generally have lower electrical conductivity. To solve this problem, this paper develops a high-conductivity, high-strength heat-resistant aluminum alloy material using an Al-Zr alloy base with the addition of metallic elements. A rolling process experiment was carried out to investigate the key process parameters at various rolling stages, achieving a match between material formulation and process. The result is a high-conductivity, high-strength heat-resistant conductor. The single-wire aluminum alloy achieved a tensile strength of 136 MPa and electrical conductivity of 61.64% IACS, with the stranded conductor maintaining 94% of its residual strength.
