Wind turbine rotor blade with an electrical heating system

Abstract

A wind turbine rotor blade including a blade root, a blade tip, a leading edge, a trailing edge, a suction side, a pressure side and a heatable surface area including at least one electrical heating element, wherein the heatable surface area covers a section of the leading edge and has a first edge facing the blade tip, a second edge facing the blade root, a third edge arranged on the suction side and a fourth edge arranged on the pressure side, characterized in that the wind turbine rotor blade includes a first layer of an electrically insulating material, wherein the first layer is smaller than the heatable surface area and is arranged on top of the at least one electrical heating element along the leading edge and such that it extends beyond the first edge.
