Abstract:
1. A tower construction for a wind turbine, the wind turbine comprising a set of blades and a nacelle enclosing at least a transmission system and power generating means, the tower construction comprising: a first structure being structurally self-supporting and adapted to support the blades, the nacelle and parts enclosed by the nacelle, said first structure defining a longitudinal direction, and said first structure having at least one wall part extending along the longitudinal direction, and a second structure being structurally self-supporting and adapted to carry one or more components of the wind turbine, said second structure being arranged along the longitudinal direction defined by the first structure, and said second structure extending along at least a substantial part of the length of the first structure in the longitudinal direction, wherein the first structure and the second structure are positioned relative to each other in such a manner that no fixed connections between the second structure and the at least one wall part of the first structure are formed; wherein the first structure and the second structure are positioned relative to each other in such a manner that any connections provided between the second structure and the at least one wall part of the first structure exert no connection force capable of resisting movement of the second structure away from the at least one wall part of the first structure; and wherein said first structure and said second structure are positioned relative to one another in such a manner that support connections on said second structure just touch an inside surface of said first structure to define abutting contact that does not affect the fatigue limit of said first structure.
