The high voltage lines that are on the drawing boards now, are quite similar to the previous ones, i.e. guyed steal frame towers, both for 400 and 220 kV.
Towers for 400 kV high voltage lines. To the left is a guyed V-tower and to the right is a guyed M-tower.
Towers for 220 kV high voltage lines. To the left is a guyed steel-framed M-tower and to the right is a guyed tubular steel tower of type M.
