MODELOS
Regarding self-supporting towers, they can be of two types, bottle model or "normal" model, differing in their structure: in the first model, the tower undergoes reductions in width in the upward direction of construction and leaves the factory in sections (construction model identical to spliced towers, but with greater strength). In the second model, the bracings are placed at the assembly height by screwing to the legs of the tower, forming the triangular section of the tower.
