A system for transmitting electrical signals and/or electrical energy via an electrically conductive medium, in which a plurality of electric wound coils is mounted on each side of the electrically conductive medium, conductors of the plurality of electric wound coils are arranged in parallel with respect to one another and each of the plurality of electric wound coils is oriented relative to each other in such a manner that winding wires are predominantly vectorially mounted in parallel, the conductors are mounted predominantly parallel to surfaces of the electrically conductive medium, the system reacts when a current is applied to the electric wound coils, thereby generating a magnetic field and generates an eddy current which circulates between an external and an internal surface of the electrically conductive medium, and a voltage is induced in the electric wound coils from the eddy current.
