| Abstract: | Taking the construction of 2 500 kV transmission lines as an example the paper demonstrates the characters of construction for 4-bundle large sectional conductor under tension stringing and its key construction process. The general analysis and comparison are given for construction methods of different processes, including double hanging points with one traction rope and single hanging point at same time and successively. For the suspension towers the stringing with double pulleys, single hanging point and 1-traction-rope for 2-conductor simultaneous will be quick in stringing speed, easy for sag measurement and adjustment, simple for installation of accessories and high in construction efficiency.
