Wind turbine blade spar cap, wind turbine blade and wind turbine

A wind turbine blade spar cap for a wind turbine blade for a wind turbine, the wind turbine blade including a down conductor, the wind turbine blade spar cap comprising:

• at least one carbon element;
• at least one conductive layer, wherein the at least one carbon element and the at least one conductive layer are electrically connected;
• and
• at least one conductive profile to electrically connect the at least one conductive layer to the down conductor of the wind turbine blade, wherein the at least one conductive profile is electrically connected to the at least one conductive layer;
• wherein the at least one conductive profile is arranged at the wind turbine blade spar cap;
• wherein the at least one conductive profile is a conductive wedge comprising a high side and a shallow side, further wherein the shallow side of the conductive wedge is directed away from the wind turbine blade spar cap.
