Abstract: A mast section (1) for a wind turbine having a longitudinal central axis (L) extending along a longitudinal direction includes at least two tubular mast elements (14) stacked along the longitudinal direction and arranged edge-to-edge at a joining plane (P). Each mast element (14) includes at least two wall segments (16), connected to one another by segment connectors (26) extending along longitudinal edges of the wall segments (16). The mast section (1) further includes element connectors (37) each extending astride the two mast elements (14), in the extension of the segment connectors (26) in the longitudinal direction. The mast section (1) further includes a plurality of element overconnectors (45), each element overconnector (45) extending astride a segment connector (26) and an adjacent element connector (37) in the longitudinal direction.

Abstract: A mast section (1) including a wall includes two tubular mast elements (14) stacked and arranged edge to edge at a joining plane (P), each element (14) comprising two wall segments (16) connected by segment connectors (26) extending along the longitudinal edges of the segments (16). The mast section (1) comprises element connectors (36) each extending across and connecting the elements (14) together. The element connectors (36) are arranged either on the inner surface (12) and outer surface (13) of the wall and the segment connectors (26) are arranged on the other surface, each element connector (36) extending at least partially opposite at least one of the segment connectors (26) in a radial direction of the mast section (1) such that the wall is placed between said element connector (36) and the segment connector (26).

Abstract: A tower section (1) for wind turbine including a wall including an inner surface (12) and an outer surface (13), the tower section including at least two tubular tower elements (14) stacked and connected together by element connectors (36) each extending astride the two tower elements, each tower element including at least two wall segments (16), connected together by segment connectors (26), the element connectors being arranged on only one of the wall surfaces and the segment connectors being arranged only on the other wall surface and no element connector facing at least partially a segment connector in a radial direction such that the wall is at no point interposed between this element connector and a segment connector.
