A WIND TURBINE BLADE AND METHOD OF MANUFACTURING A WIND TURBINE BLADE

摘要

A wind turbine blade comprising a lightning protection system is provided. The lightning protection system comprises a lightning conductor located along a longitudinal portion of the wind turbine blade and is coupled to an electrical ground. A lightning receptor module is arranged on an external surface of the wind turbine blade and electrically coupled to the lightning conductor. An elongate receptor band is installed on the external surface of the wind turbine blade over the lightning receptor module and the receptor band is arranged to receive a stroke of lightning and transfer electrical current from the lightning stroke to the lightning conductor through the lightning receptor module. Further the elongate receptor band comprises a crease in a longitudinal cross sectional profile of the elongate receptor band.A method of installing a lightning protection system on a wind turbine blade is further provided.
