Wind turbine blade including two lightning down conductor arrangements and wind turbine

A wind turbine blade comprising two electrically conductive spar caps, two lightning down conductor arrangements, and a further electrical conductor, wherein the spar caps and the lightning down conductor arrangements extend along a spanwise direction of the blade at least between a root-side end portion and a tip-side end portion of the blade, wherein each of the spar caps is electrically connected to only a respective one of the lightning down conductor arrangements within a section of the blade between the root-side end portion and the tip-side end portion, wherein the further electrical conductor is electrically connected within the section to only one of the spar caps and/or to only one of the lightning down conductor arrangements, and wherein the further electrical conductor is connected to at least one of the spar caps and/or at least one of the lightning down conductor arrangements at a plurality of connection positions, wherein the plurality of connection positions are offset in the spanwise direction of the blade, and wherein the further electrical conductor comprises one or more signal cables and a shield conductor, wherein the shield conductor is electrically connected to at least one of the spar caps and/or at least one of the lightning down conductor arrangements.
