INSULATION OF A HEATING MAT OF A WIND TURBINE BLADE

Provided is a rotor blade of a wind turbine including a leading edge section with a leading edge and a trailing edge section with a trailing edge, wherein the leading edge and the trailing edge divide the surface of the rotor blade into a suction side and a pressure side. The rotor blade further inc...

Beschreibung
Zusammenfassung:	Provided is a rotor blade of a wind turbine including a leading edge section with a leading edge and a trailing edge section with a trailing edge, wherein the leading edge and the trailing edge divide the surface of the rotor blade into a suction side and a pressure side. The rotor blade further includes a blade shell for defining the outer shape of the rotor blade and a heating mat for anti-icing and/or deicing purposes which is arranged upon the blade shell. In the outboard region of the rotor blade, the heating mat is substantially or completely covered by a protective shield made of an electrically insulating polymer material. Use of a protective shield made of electrically insulating polymer material for electrical insulation of a heating mat in particular, against lightning strikes is also provided.
