A wind turbine with a tower, a nacelle, a main shaft, a hub and blades is provided. The wind turbine also includes a liquid medium distribution system for transport of liquid medium in the wind turbine. The liquid medium distribution system has a first distribution sub-system located in the tower, a second distribution sub-system located in the nacelle, a third distribution sub-system located in the hub, a tower-nacelle-interface connecting the first distribution sub-system to the second distribution sub-system, and a nacelle-hub-interface connecting the second distribution sub-system to the third distribution sub-system. Further, a method of transporting liquid medium in a wind turbine is provided.
