Abstract: A structure for supporting electric power transmission lines that aims to obtain a better stress and strain behaviour providing a higher ultimate economy. The preferred embodiment is directed to a structure that comprises a metallic vertical structure (101) having: a lower tubular frustum shape (103) with a smaller end (104) and a larger end (105), wherein the smaller end is on the bottom and the larger end on the top; an upper frustum shape (106) with a smaller end (107) and a larger end (108), wherein the smaller end is on the top and the larger end on the bottom; and wherein the larger end of the lower frustum is adjoined to the larger end of the upper frustum; line supporting members (109); side supporting elements (110) attached in the adjoining region (111) of the lower and upper frustums, and extending between the attachment and an anchoring base (113); and wherein the adjoining region is below the line supporting members.

Abstract: This invention relates to metallic towers or the like utilized for electric power transmission lines, telecommunications, wind energy generators and other applications. The standard sections used in lattice towers of the prior art have structural and aerodynamic deficiencies. To overcome the drawbacks and problems the prior art one aspect of the present invention is directed to a metallic tower comprising lattice members with a channel section, wherein the length of the channel web is smaller than the length of the channel legs.
