Lightning protection system for a wind turbine blade

A wind turbine blade comprising a first blade shell part (36) and a second blade shell part, wherein the first blade shell part comprises:

• a first blade component extending along a longitudinal axis of the wind turbine blade and comprising one or more first carbon fibre structures, the first blade component being at least partially embedded in the first blade shell part;
• a first elongate metallic element arranged in direct contact with the first blade component, at least part of the first elongate metallic element being positioned between the first blade component and an outer surface of the first blade shell part;
• and
• a first lightning receptor arranged in electrical contact with the first elongate metallic element and extending to or near an outer surface of the first blade shell part, wherein the first lightning receptor does not extend through the first blade component,
• and/or wherein the second blade shell part comprises:
• a second blade component extending along the longitudinal axis of the blade and comprising one or more second carbon fibre structures, the second blade component being at least partially embedded in the second blade shell part;
• a second elongate metallic element arranged in direct contact with the second blade component, at least part of the second elongate metallic element being positioned between the second blade component and an outer surface of the second blade shell part;
• and
• a second lightning receptor arranged in electrical contact with the second elongate metallic element and extending to or near an outer surface of the second blade shell part, wherein the second lightning receptor does not extend through the second blade component.
