ABSTRACT:
The invention relates to a wind turbine comprising a rotating part including a rotor with at least one blade and a wind turbine hub with at least one enclosure structure or similar wall structure, and a stationary part including a nacelle with at least one enclosure structure or similar wall structure. At least one of said parts comprises a conductive film layer of said enclosure structure with connection to a ground potential, where said film layer forms a shield enclosing said part or parts and protects against electromagnetic fields. The invention also relates to a method to manufacture said enclosure structure.
