Delta4000 N133The Nordex Group is extending its Delta4000 product series to include a turbine especially designed for strong-wind sites: the N133/4.8. The rotor blade from the N131 turbine has been integrated into the Delta4000 series for the N133/4.8. By combining this rotor blade with the hub and nacelle of the N149/4.0-4.5 it was possible to increase the rotor diameter to 133 metres.
The company raised the maximum output to 4.8 MW. The new technical specifications embodied in the Delta4000 series’ first turbine, the N149/4.0-4.5, such as an improved service concept, a mobile crane solution and a more efficient electrical system, are also integral to the new N133/4.8. 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 turbine comes available with hub heights of 78, 83 and 110 metres and the start of series production of the N133/4.8 is scheduled for 2019.
