AW125/3000
El aerogenerador AW125/3000 es la solución idónea para vientos medios con menores turbulencias
La versión del AW3000 de 125 metros de rotor optimiza la captación de energía en emplazamientos de velocidades de viento medias con baja intensidad de turbulencias. Certificado para las clases IEC IIb/IIIa, ACCIONA Windpower ya tiene comprometido el suministro de más de 500 MW (a octubre de 2014) para su instalación en diferentes países en los próximos meses. Está disponible en torre de acero de 87,5 m y en torre de hormigón de 100 m, 120 m y 137.5m de altura de buje.
