Abstract: Provided is an electrical connection system for a wind turbine blade that allows sharing the current between all conductors, in order to avoid voltage differences between them, avoiding internal sparks between pultruded plates, in a spar cap of the wind turbine blade. A second aspect is a wind turbine which in turn includes the wind turbine blade including the electrical bonding system. A third aspect is a method for electrically connecting conductive caps in a wind turbine blade.

Abstract: An anti and/or de-icing blade and manufacturing method for said blade including a pressure side shell and a suction side shell, the shells including at least one electrical connector layer extending from the leading edge towards the trailing edge, at least one heating elements layer electrically in contact with the electrical connector layer, glass fabric layers at least inwardly in contact with the electrical connector or with heating elements layer, a connector component extending transversally through the glass fabric layers and being electrically connected with the electrical connector layer and with a metallic block which is drilled by an inter-connector so that the electrical connector layers from each shell are electrically connected and the blade is able to be heated when electrically fed from power source.
