Claims15
A blade for a wind turbine including a structure having:
- a suction side and a pressure side extending between a leading edge and the trailing edge,
- a pair of conducting or semi-conducting elements, further wherein a first conducting or semi-conducting element of the pair of conducting or semi-conducting elements forms a first spar cap and a second conducting or semi-conducting element of the pair of conducting or semi-conducting elements forms a second spar cap, and wherein at least one of the first spar cap and the second spar cap is a blade heating element or includes a blade heating element,
- wherein the blade further includes:
- a thermally conducting electrical insulation, at least partially in contact with the structure and distanced from the first spar cap and the second spar cap.
