Abstract: A lightning current transfer arrangement for a wind turbine enables lightning current and electrostatic discharge current to be discharged between first and second parts of the wind turbine that are rotatable relative to each other. The lightning current transfer arrangement comprises 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 comprises a slider elastically biased towards the slideway, where the slider comprises a slide piece formed of a conductive plastic material, and a metal electrode rigidly coupled with the slide piece.
