A wind turbine rotor blade is assembled from a first and a second rotor blade half shell made of a fiber-reinforced plastics material. An electrical heating arrangement includes a first heating element connected to the first rotor blade half shell and having a blade root end and a blade tip end and a second heating element connected to the second rotor blade half shell also having a blade root end and a blade tip end. The heating arrangement also includes a third heating element connected to the rotor blade half shells and having a blade root end and a blade tip end. The blade tip ends of the first, second and third heating elements are mutually electrically connected. The blade root ends of the first, second and third heating elements are connected to respective electrical connecting lines.

Wind turbine rotor blade having an electrical heating arrangement and method of making the same

The invention relates to a wind turbine rotor blade having a blade root, a blade tip, two interconnected rotor blade half shells, which include a fiber-reinforced plastics material, and an electrical heating element, which is arranged on an outer side of the rotor blade and has a blade root end and a blade tip end, wherein the blade tip end is connected via an electrical line leading to the blade root and at least a first segment of the electrical line, which is arranged on an inner side of one of the rotor blade half shells, is made of a carbon fiber material. Further, the present invention relates to a method for making a wind turbine rotor blade having an electrical heating element.
