Wind Power
Wind power is one of the fastest-growing renewable energy technologies. Global installed wind-generation capacity onshore and offshore has increased by a factor of almost 75 in the past two decades. However protection of these is paramount as they are subjected to the most aggressive environments. They are constantly exposed to humidity with high salinity and to intensive UV-radiation.
Thankfully TSZ/TSA wind towers provides the necessary protection which will remain effective during the designed 25–40 years’ lifetime of these wind farms.
The Wind towers sections are initially grit blasted to SA3 standard then the various areas are zinc coated with typically 60-120 microns of zinc or Zinc/aluminium. The Arc sprayed zinc coating is applied to the main tower sections and also areas that are more susceptible to corrosion due to assembly damage and normal usage. Specifically, these areas include the studs, brackets & connection flanges. For external corrosion protection of offshore monopiles the application of Arc sprayed Aluminium + sealer to just below the minimum sea water line to several meters below the sea bed is used .
This form of protection gives an impressive cost–benefit relationship.
