A Study or the Use of Aluminum Guyed Towers for Extra-High-Voltage Transmission Systems

Detailed studies carried out by the authors indicate that for the topographic conditions in central British Columbia in Canada, the use of guyed transmission structures offers worthwhile savings over use of conventional self-supporting towers for extra-high-voltage (EHV) transmission systems. However, the self-supporting tower is recommended for the mountain sections of British Columbia. The advantages and disadvantages of both types of structure are considered, together with a description of a series of tests carried out on a guyed aluminum tower to determine erection methods and costs and to evaluate stability under various loading conditions.
