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.
