Reliable pitch tube for a blade pitch control system of a wind turbine

A transmission for a wind turbine, the transmission comprising a pitch tube which comprises a tube body extending from a first axial end to a second axial end, for passage of supply lines through the transmission, said tube body designed of 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, the transmission further comprising a transmission housing, wherein the first axial end of the tube body on a generator-side axial side of the transmission housing protrudes from the transmission housing and/or the second axial end of the tube body on a rotor-side axial side of the transmission housing facing away from the generator-side axial side protrudes from the transmission housing.
