Abstract
A wind turbine blade integrating a lightning protection system is provided. The wind turbine blade includes one spar cap formed by carbon plates stacked together; and a first down-conductor placed alongside the tip region of the spar cap, and a second down-conductor placed alongside the root region of the spar cap. The first down-conductor extends from the spar cap's tip end to the mid region, and terminates at a first down-conductor's end adjacent a first region of the spar cap which extends from a cross-sectional area of the spar cap which area is equal or higher than 75% of the maximum cross-sectional area of the spar cap, which is closest to the spar cap's tip end, to a cross-sectional area of the spar cap which is 100% of the cross-sectional area of the spar cap, being 100% of the cross-sectional area the one closest to the spar cap's root end.
