AW132/3000
El AW132/3000 es la última evolución de la plataforma de 3 MW, diseñado para vientos bajos con bajo nivel de turbulencias.
Con una de las mayores áreas de barrido del segmento, 13.720 m2, optimiza la captación de energía y reduce significativamente el coste de la energía en emplazamientos de viejos bajos (clase IEC IIIb). Está inicialmente disponible con torre de hormigón de 120 metros de altura de buje y pronto lo estará con torre de acero de 84 m, lo que constituye una solución única y eficiente para emplazamientos con limitaciones de altura y vientos bajos.
