Progress in Multi-Performance Enhancement Technology of Heat-Resistant Aluminum Alloy Conductor

Abstract

Al-Zr heat-resistant aluminum alloy conductor are widely used in large-capacity overhead conductors due to its excellent thermal stability, but there is a mutual constraint relationship between electric conductivity, heat resistance, and strength. This article reviews the research progress on the synergistic improvement of mechanical-electrical-thermal properties of heat-resistant aluminum alloy conductor from the perspective of component design optimization. The micro-alloying control technology based on traditional experiment and the new ideas for component design based on advanced material calculation methods
