Abstract (en)
[origin: WO2009132659A2] The invention relates to a tower section for assembling a wind turbine tower. The tower section comprises a flange at least at one end of the tower section. The flange is provided with holes for the connection elements. The flange have a first array of holes, where each hole is arranged in a first angle (a) relative to a longitudinal axis of the tower section, and a second array of holes, where each hole is arranged in a second angle (ß) relative to the longitudinal axis. The first angle (a) is different from the second angle (ß). The invention also relates to a foundation comprising a flange, where the flange of the foundation has characteristics corresponding to the characteristics of the tower section flange. The invention also relates to a wind turbine tower and to a wind turbine.
