US 10,330,085 B2 · Tower for a wind turbine

Abstract

A tower for a wind turbine may include an upper tower portion and a lower tower portion. The upper tower portion may include a tubular tower, and the lower tower portion may include a lattice tower. To improve ergonomics and work safety and make it possible to obtain a structural design with optimized forces, the lower tower portion may include a central tube positioned centrally within the lattice tower. Further, the central tube may have a smaller diameter, at least in certain portions, than at least part of the tubular tower of the upper tower portion. The tower may also include a transition piece between the upper tower portion and the lower tower portion. The transition piece may join the tubular tower of the upper tower portion and the central tube of the lower tower portion.
