Modular wind tower

A modular tower (1), comprising:

• a plurality of modules (57, 84) each having a polygonal cross-section that narrow from bottom to top of the modular tower (1);
• each module (57, 84) comprises a plurality of tower elements (22) made of steel or composite material;
• the tower elements (22) are mounted laterally to each other;
• wherein as tower height increases, the tower elements (22) of the modules (57, 84) have one or more inner walls (30) each fixed to a single respective tower elements (22) to increase material thickness of the tower elements (22);
• the tower elements (22) of the modules (57, 84) are mounted to each other vertically on y axis by module connectors (50), wherein the module connectors (50) transmit forces acting on the modular tower (1) to a foundation uninterruptedly along the modules (57, 84) and ensure installation of the modules (57, 84);
• the module connectors (50) are factory installed on modules (57, 84) of the tower elements (22);
• a top flange fixed to a topmost module, which allows mounting a nacelle to the modular tower (1);
• and
• a foundation module, which has a same cross-section as a lowest module;
• wherein the plurality of modules (84) having multi-walls and consisting of segments (82) in which at least one inner wall (30) is mounted on an inner surface of the tower elements (22) with wall bolts (37);
• wherein an outer circumference of an upper edge section of the module (84) is exactly equal to an outer circumference of a lower edge section of an upper module;
• wherein an outer circumference of a lower edge section of the module (84) is exactly equal to an outer circumference of an upper edge section of a lower module;
• and
• wherein thanks to these features of their cross-sections, it is ensured that the modules (84) are mounted to each other only face-to-face.
