摘　　要：1 000 kV黄河大跨越工程跨距大,耐张段长,选择合理的导线对于保证大跨越的安全、降低塔高、节省工程投资具有重要意义。此文依托榆横—潍坊线路黄河大跨越工程,从导线材料、导线结构、制造条件方面选取不同型号特强钢芯高强铝合金导线方案,进行输送容量、电磁环境、机械特性和经济性等方面的比较,推荐1 000 kV榆横—潍坊线路黄河大跨越工程导线采用6 X JLHA1/G4A-630/170特强钢芯高强度铝合金绞线。1000kV Yellow River Crossing Project has large span and long strain section,so it has great significance to select reasonable conductors to ensure the safety of large span ,reduce tower height and save project investment.Relying on Yuheng-Weifang Line of Yellow River Crossing Project,this paper selects different models of high strength aluminum alloy conductors with extra-strong steel core in terms of conductor material,conductor structure and manufacturing conditions to make a comparison in transmission capacity, electromagnetic environment,mechanical properties and economical efficiency,and recommends 1000kV Yuheng-Weifang Line of Yellow River Crossing Project should use 6 X JLHA1/G4A-630/170 high stranded aluminum alloy conductor with extra-strong steel core. strength
