The preparations took a year; finally at the end of May, the test rig known as the FVA nacelle was officially inaugurated at the RWTH Aachen. A joint project is currently in progress there to test the stresses on drive components of wind turbines at the Centre for Wind Power Drives (CWD).


Prysmian breaks voltage record

For the first time in the cable industry, the Prysmian Group achieved voltages of 700 and 600 kV in high-voltage DC transmission (HVDC). This means that the company achieves an energy transmission capacity increase of up to 15 percent and improved grid reliability. (Photo: Prysmian Group)

The Prysmian Group has announced two milestones in energy transmission: the company's new mass-impregnated 700 kV MI-PPL and the 600 kV cross-linked polyethylene cable systems (XLPE) for applications in high-voltage DC transmission (HVDC) field have been successfully tested and have also set new voltage records.
