依托1 000 kV锡盟—南京（济南—徐州段）特高压交流工程，参考国内750、500 kV同塔双回输电线路的研究成果及运行经验，通过技术经济比较，给出1 000 kV特高压交流同塔双回线路推荐换位塔型式，研究成果可应用于工程设计。

For Jinan-Xuzhou part of 1 000 kV UHV Ximeng-Nanjing project, the transposition tower type is recommended of 1 000 kV UHV AC double-circuit transmission lines on same tower, by the analysis of technical and economic comparison, and by referring the research achievements and operating experience of domestic 750 kV and 500 kV double-circuit transmission lines on same tower. The research results in the paper can be applied to engineering design.
