Download WindpowerUpdate 15 - Nordex

Numerous detail solutions testify to the maturity of the series,
while the oil-cooling system marks a new development for
Nordex: the turbine is fitted with a permanent pressurized
circulating lubrication system and a larger filter volume. A temperature-based
pump control system avoids major fluctuations
in the temperature of the oil sump, protecting the transmission
and the bearings from excessive wear and ensuring reliable
operations.
If it does become necessary to replace a component, the expense
involved is limited. Even key components can be removed
without dismantling the entire drive line. The modular assembly
concept also heightens flexibility during the construction phase.
The maximum weights are 40 tons, representing an advantage
in terms of crane costs and facilitating assembly in rough terrain.
One particular advantage in densely populated regions is
the low noise levels exhibited by the N80/N90 series during
operation. Whereas favourable readings of less than 104 dB are
already achieved during operation at the turbine’s rated capacity,
noise emission drops to below 100 dB in the reduced-noise
mode. Thus, by lowering the speed in sound-critical locations,
it is possible for the turbine to continue producing electricity
even during the night.
... and the hub are prepared to be installed.

The first blade is mounted to the hub. The installation of the powerful wind turbine is completed.
