Abstract: A de-icing arrangement of a wind turbine rotor blade is provided. The de-icing arrangement includes an electrically conductive mat, an electrically conductive band for distributing an electric current along a first edge of the mat, and a current supply connector for connecting the band to a current supply, wherein at least the electrically conductive mat is embedded in the body of the rotor blade. A wind turbine including a number of rotor blades including such a de-icing arrangement according, and a current supply for connecting to the de-icing arrangements of a rotor blades. A method of incorporating a de-icing arrangement in a wind turbine rotor blade is also provided.
