| 摘 要： | 大跨越输电线路的增容改造,需要在不增加跨越直线塔荷载的情况下,提高导线的允许温升和载流量,并且满足安全距离的要求,特强钢芯高强耐热铝合金导线是较为理想的选择。±500kV葛沪直流吉阳大跨越的增容改造工程中,从导线材料、载流量、电气性能、机械性能、经济性能等方面进行综合比较,最终选择2×KTACSR/EST-630/360导线作为推荐方案。

| Abstract: | Large crossing lines upgrading requires higher acceptable temperature rise and load current of the conductor,as well as satisfies safe clearance requirements without incurring more tower loadings.Therefore,high-strength heat-resistant aluminum alloy conductor ultra-high strength steel reinforced is an ideal choice.In Jiyang large crossing of ±500 kV Ge-Hu Line project,2 KTACSR/EST-630/360 conductors are recommended after comprehensive comparisons in material,bearing capacity,electric performance,economy,etc. |
