1. A conductive connection between a Carbon Fiber Reinforced Polymer (CFRP) element and one or more down conductor(s), the CFRP element being electrically conductive and comprises a face, the conductive connection comprising:
an interface conductive patch provided on the face of the CFRP element for electrically connecting the CFRP element with the interface conductive patch, the interface conductive patch is electrically connected with one or more down conductor(s);
wherein the one or more down conductor(s) comprises a down conductor comprising a sheet and/or a cable, wherein the interface conductive patch comprises a conductive connection patch point being configured to electrically connect the interface conductive patch to the down conductor comprising the sheet and/or the cable; and
wherein the conductive connection patch point comprises a first disc and a second disc, wherein the first disc and the second disc are arranged on opposite sides of the conductive connection patch and being connected to each other.
