Test Analysis of 220 kV Rotating Transmission Angle Tower

As the requirements for the protection of environmental water in the construction of transmission lines have increased, the position of the tower in steep mountainous areas often fails to meet the requirements because of the difference in tower legs, which causes damage to the original landform, thus resulting in the change of the path and the increase of the project investment. In this paper, we optimize the design of a rotating steel tower to adapt to the steep terrain of mountainous areas and reduce the base surface opening. The feasibility of the proposed rotating tower optimization design is demonstrated by analyzing the real test data of the rotating tower.
