Abstract

Abstract: In view of low conductivity and high line loss of heat-resistant aluminum alloy wire compared with those of conventional ACSR in China, a method to improve the conductivity of heat-resistant aluminum alloy conductors is discussed. In this method, the aluminum alloy composition and microstructure are controlled by the micro-alloying effect,combining with the adjustment of zirconium content. The samples of the heat-resistant aluminum alloy wire with high conductivity and low cost were prepared by tests in the laboratory. Moreover, the conductors were successfully verified in continuous casting and rolling production line in a cable factory, which had laid a foundation for production and application of heat-resistant aluminum alloy conductors with high conductivity.

Key words: heat-resistant aluminum alloy conductor, augmented capacity conductor, transmission line, conductivity
