Abstract
A wind turbine blade with a lightning conductor, where said lightning conductor is formed by one or more oblong strips (1, 2, 3) of carbon fiber-reinforced plastics preferably forming part of the wind turbine blade. In this manner the oblong strips (1, 2, 3) of carbon fiber-reinforced plastics both reinforce the blade and divert the lightning.
Claims7
A wind turbine blade of glass and/or carbon fibre-reinforced plastics including an inner lightning conductor cable, the wind turbine blade comprising:
- a blade wall including oblong strips containing carbon fibre-reinforced plastics;
- and
- conductors that interconnect the inner lightning conductor cable and the oblong strips at regular intervals.
