Abstract

The limb width and the limb thickness of the large size angle steel are very great, section area is more greater than that of the angle steel in the conventional power transmission tower, which can greatly improve bearing force of the single member. It is considered feasible after analysis that the 300mm single limb large size angle steel is applied to substitute the double combination angle steel; take the JC1 angle tower in ±1100kV Huaidong Transmission ultra-high voltage DC engineering as the analysis object, it optimizes the slope of the tower body and the root open size, economic analysis is carried out when the main member applies the combination angle steel and the large size angle steel respectively. Results show: Weight of the JC1 tower which main member applies the 300mm large size angle steel is 6%~10% lower than that of the combination angle steel tower. Price of every base of the steel tower is 7%~11% lower than that of the combination angle steel tower, which has high economic and social benefit.
