Background
With the continuous and rapid development of social economy, the demand of society on electric power is continuously rising, the construction of the electric transmission line is rapidly developed, the path corridor of the electric transmission line is more and more tense, and the selection of the tower position of the line is more and more difficult, for example, when the electric transmission line is wired in special and complex mountain areas such as Guangxi karst landform, Xinjiang Danxia landform and the like, the tower position is often difficult to be established due to the limitation of topography or landform or the electric air gap after the wire is windage-biased is tense, so that the line is changed in a large range, and the line construction period.
Meanwhile, with the expansion of power grid coverage, tower structures in areas such as scenic spots, cities and towns have increasingly serious influence on environmental landscapes. Particularly, for the power transmission line in the environment sensitive area, besides emphasizing practicability and scientificity, attention should be paid to fusion and aesthetic design of the power transmission line and the surrounding environment, how to combine the power transmission line and the natural environment design together, and aesthetic influence on the environment sensitive area is reduced, so as to better meet social development and environmental requirements.
Therefore, it is necessary to research how to use the actual terrain according to the special, complex and environmentally sensitive mountain conditions, and to build a suspension cable in the air between two adjacent mountains to support a line conductor (the suspension cable is directly fixed on a mountain rock or fixed on a bracket), so as to replace the original ground iron tower support, and meet the line construction requirements of the special mountain landform.
