Abstract
A lightning current transfer arrangement for a wind turbine is provided, to enable lightning current and electrostatic discharge current to be discharged from a first and a second part of the wind turbine being rotatable relative to each other. The lightning current transfer arrangement is arranged to provide electrical contact between the first and second parts, and has a current transfer unit electrically coupled to the first part, and an electrically conductive slideway electrically coupled to the second part, and rotatable relative to the current transfer unit. The current transfer unit further has a slider elastically biased towards the slideway, where the slider comprises a slide piece made of conductive plastics and contacting the slideway, and an electrode made of metal and directed towards the slideway, the electrode and the slide piece being rigidly coupled.
