The invention relates to a lightning arrester system for wind generator blade, which replaces the standard main copper cable and which employs two strips of copper that extend along the entire length of the beam such as to be in direct contact with the carbon fibre. In this way, the carbon fibre laminate and the copper strip are always at the same potential, thereby preventing any possible arc-over between the two elements. The carbon fibre laminate is barely affected by the passage of current owing both to the electrical characteristics of the two components and to the selected configuration which conveys most of the current through the copper strips. In addition, with said novel system it is possible to position intermediate receivers on the actual laminates and in direct contact with the copper strip.
