Abstract (en)
[origin: WO2017045993A1] The invention relates inter alia to a tower for a wind turbine, with an upper tower portion (2) and a lower tower portion (4, 4'), wherein the upper tower portion (2) comprises a tubular tower (6), wherein the lower tower portion (4, 4') comprises a lattice tower (8, 8'). The object of allowing improved ergonomics and work safety and making it possible to obtain a structural design with optimized forces is achieved by the lower tower portion (4, 4') comprising a central tube (10, 10') arranged centrally within the lattice tower (8, 8'), and by the central tube (10,') having a smaller diameter, at least in certain portions, than at least part of the tubular tower of the upper tower portion.
