Abstract: The popularization of the steel tubular tower in UHV projects has raised new requirements for the tower reliability and economics. By comparing the materials for steel tubular towers and those for angle steel towers and considering the structural characteristics of the steel tube tower, a method for improving the economics of the UHV steel tube tower by reducing the joints is advanced. The application of the forging flange in UHV steel tubular towers is analyzed in detail and a new method for forging flange fine designing is developed. In addition, combined with the design of the EHV/UHV quadruple-circuit steel tubular tower, the feasibility and economics of the related methods are studied. The research shows that in UHV steel tubular tower designing, the proportion of forging flanges can be minimized through several ways, such as strength classification, distribution optimization and material selection. All these can further improve the economics of the UHV steel tubular towers.

Key words: UHV, steel tubular tower, forging flange, design optimization, tower economics
