The Nordex Group is extending its Delta4000 product series introduced in fall 2017 to include a wind turbine especially designed for strong-wind sites: the N133/4.8. The rotor blade from the proven N131 turbine has been integrated into the Delta4000 series for the N133/4.8.
The N133/4.8’s hub heights of 78, 83 and 110 m ensure that any strict height restrictions can be complied with. This means that even under complex site conditions and with height restrictions of 145 m, the turbine can be operated efficiently and safely.
By combining this rotor blade with the hub and nacelle of the N149/4.0-4.5, also from the Delta4000 product series, it was possible to increase the rotor diameter to 133 meters. Nordex has also raised the maximum turbine’s output to 4.8 MW to make optimal use of high wind speeds. This results in an additional yield of up to 39% for the N133/4.8 compared to the previous N100/3300 model, which is also optimized for strong-wind sites.
The technical innovations embodied in the Delta4000 series’ first turbine, the N149/4.0-4.5, are also integral to the new N133/4.8, resulting in a significant drop in cost of energy. These features include an improved service concept, a mobile crane solution, and a more efficient electrical system.
As with the N149/4.0-4.5, the sound power level of the N133/4.8 is particularly low. Equipped with serrations, the N133/4.8 turbine’s sound level is limited to just 106 dB(A) when under full power, and this can be reduced as required, depending on location, to 98 dB(A) by using numerous different operating modes.
The fully flexible control system can even be adapted for special cases such as public holidays or certain times of the day.
The N133/4.8 is particularly suitable for regions with strong winds in north-west Europe, such as Great Britain and Norway, as well as for sites with high wind speeds in Turkey, Australia, and Central and South America. The start of series production of the N133/4.8 is scheduled for 2019.
