| 摘 要： | ±800kV云广特高压直流线路工程为世界首创，其铁塔塔身截面大、横担重量大，长度长，组立施工的关键是横担起吊及安装。通过对3种吊装方案的比较，建议采用将横担分为左右两段分别起吊的方案，并选用700mm×700mm的全钢抱杆。

| Abstract: | The Yunnan - Guangdong ±800 kV DC project is the first one of UHVDC transmission at so high voltage level in the world. The great towers in this project have large cross section, heavy across arm and long length. To assemble and erecte the across arm is the key issue for the tower building. This paper compares 3 hoisting solutions, and suggests that the scheme of hoisting on both left and right sides of the across arms with 700 mm × 700 mm all-steel poles is the best one. |
