Abstract

A spar cap assembly for a rotor blade of a wind turbine is provided. The spar cap assembly (100) comprises a stack (50) of layers (51, 52, ...) of carbon fiber composite material, wherein the layers are stacked in a thickness direction (111) and wherein the stack (50) extends in a longitudinal direction (110), and further comprises a lightning conductor (40) of a lightning protection system extending along the stack of layers. At least one potential equalization assembly (120) configured to electrically connect the stack (50) of layers of carbon fiber composite material to the lightning conductor (40) provides an equipotential bonding (121) at an equipotential bonding position (122) in the longitudinal direction. Two or more longitudinal contact ranges are arranged in longitudinal direction (110) next to each other, wherein each longitudinal contact range (10, 20, ...) comprises at least a first sheet (11, 21, ...) of conductive material that is arranged on and in direct electrical contact with a layer (51, 52, ... ) of the stack (50) and that rests against the lightning conductor (40).
