    2008-4-1 · The cables have a conductor area of 16 mm 2 and consist of several copper strands. This results in a rated current density of 1.6 A/mm 2. However, the generator can handle a higher current and also a higher voltage than rated. The turbine's power absorption can thereby be controlled electrically, which is important in strong and gusty winds.
