Nordex introduces two new turbines from its multi-megawatt Generation Delta platform. For sites with moderate winds Nordex is launching the N117/3600 with an installed capacity of 3.6MW. This gives the turbine a 20% higher-rated output than its sister model, the N117/3000. For light-wind sites Nordex has also raised the rated output by 20 per cent by introducing the N131/3600 with an installed capacity of 3.6MW.
The sound emissions of the N131/3600 are limited to a max. 106.4 dB(A) and at 105 dB(A), the N117/3600 has the same sound emissions as the N117/3000. Furthermore, Nordex offers both machines with serrations, which reduce the sound emissions by an additional 1.5 dB(A) in each case. These serrations can be found on the trailing edge of the rotor blades and serve to reduce the aerodynamic sound power level overall. The company offers the N131/3600 with tower heights of 84 to 112 metres, and for Scandinavia, up to 134 metres. The N117/3600 is available with tower heights of from 91 to 141 metres. Nordex plans to install the first of each of these turbine types before the end of 2016. The series ramp-up for both turbines is scheduled for summer 2017. The type test results will be available this year and the type certificates are expected in mid-2017.
