Transition piece for wind turbine tower

A transition piece for a wind turbine tower with a nacelle and blades, an upper part of the tower being formed by tubular segments and a lower part of the tower by connection of several lattice modules composed of diagonal and horizontal columns, the transition piece comprising:

• a central hollow frustoconical piece connected to an upper ring and to a lower ring, said upper ring being connected to a plurality of crossbars of the transition piece, and the lower ring connected to a plurality of radial columns of the transition piece, and
• three connectors, each connector of said three connectors being connected to a crossbar of the plurality of crossbars, two radial columns, and two connection profiles that keep the three connectors joined together;
• and
• a pair of radial columns arranged between a respective connector of the three connectors and the lower ring;
• wherein the crossbars are arranged between the upper ring and a respective connector of the three connectors;
• and
• wherein the pair of radial columns forms an angle between 65° to 75° , measured between a normal axis of the central hollow frustoconical piece and a longitudinal axis of a radial column of the pair of radial columns that is proximate to the normal axis of the central hollow frustoconical piece.
