摘要/Abstract

摘要： 针对目前国产耐热铝合金导线较常规钢芯铝绞线的导电率低、输电线损较高阻碍其大范围应用的技术问题,介绍研制新型耐热铝合金导线的思路。以价格相对低廉的常规工业纯铝锭（99.7%Al）为原料,利用微合金化作用进行铝合金成分及微观组织结构的控制,并通过Zr元素含量的优化调整,在实验室采用小试线方式制备出高导电率、低成本的耐热铝合金单丝样品。目前,该技术已通过线缆生产车间连铸连轧生产线的试验验证,为后续高导电率耐热铝合金导线的生产及示范应用奠定了良好基础。

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
