The Nordex Group is extending its Delta4000 product series introduced in 2017 to include a turbine designed for strong-wind sites.
The rotor blade from the N131 turbine has been integrated into the Delta4000 series for the N133/4.8. Combining this rotor blade with the hub and nacelle of the N149/4.0-4.5 (also from the Delta4000 product series) increases the rotor diameter to 133 meters.
Nordex has also raised the maximum output to 4.8 MW in order to make optimal use of high wind speeds, resulting in an additional yield of up to 39% for the N133/4.8, the company states.
The features included in the N149/4.0-4.5 — such as improved service concept, a mobile crane solution, and a more efficient electrical system — are also included in the new N133/4.8. Equipped with serrations, the N133/4.8 turbine’s sound level is limited to 106 dB(A) when under full power. This reportedly can be reduced as required, depending on location, to 98 dB(A) by using different operating modes.
Start of series production of the N133/4.8 is scheduled for 2019.
