摘要
在云南至广东±800kV直流输电线路工程第13标段架线施工过程中,成功应用了"一牵六"环形牵引张力展放6分裂大截面钢芯铝绞线LGJ-630/45施工工艺,将张力架线牵引场、张力场设于同一场地,通过转向场实施180°转向完成环形牵引,有效解决了高山大岭地区张力架线施工牵张场地选择困难的难题,对类似工程张力架线技术改进具有参考价值。
The construction technology of ＂1-pulling 6-wire＂ loop stringing 6-bundle large-sectional LGJ-630/45 ACSR was successfully adopted in Section No.13 line stringing of ±800 kV Yunnan-Guangdong DC Transmission Line.The stringing under tension pulling yard and tension yard are located at the same yard,where the loop pulling is completed through 180° steering on the steering yard.The technology has solved the problem that it is difficult to choose a pulling yard for stringing construction under tension in high mountain areas,which will be a reference for similar stringing construction under tension.
