| Abstract: | The basis of height of 750 kV single and double-circuit AC transmission line is analyzed in this paper. Considering that the greater part of 750 kV transmission line path Xining-Yongdeng-Baiyin is untraversed, the height of AC double circuit transmission lines on the same tower in this project can be reduced about 2.7~4.5 m, and the construction budget can decrease about ten million yuan |
