Abstract: A pitch tube for a blade pitch control system of a wind turbine includes a tube body extending from a first axial end to a second axial end, for passing supply lines through a transmission. The tube body is designed in multiple parts and made of a non-conductive material only in an axial partial region in order to electrically insulate the first axial end in relation to the second axial end and/or in order to electrically insulate the tube body in relation to the transmission.

Abstract: A bearing assembly for a pitch tube of a wind power plant includes a transmission shaft, a bearing cartridge for mounting and sealing the pitch tube with respect to the transmission shaft, a fastening flange which is configured by the transmission shaft or by the pitch tube for fastening the bearing cartridge in a non-rotational manner, and an insulation element which is fastened via a first fastening element to the fastening flange and via a second fastening element to the bearing cartridge for the electrical insulation of the pitch tube with respect to the transmission shaft. With the aid of the bearing cartridge which is fastened in an electrically insulating manner by the insulation element, a mechanically and electrically operationally reliable passage of the pitch tube through the transmission of a wind power plant is made possible in an inexpensive and simple manner.
