Abstract
An installation for the non-contact transfer of energy includes at least one primary conductor system and a pick-up, including at least one secondary winding inductively coupled to the primary conductor system, the secondary winding including at least one flat ribbon cable, which has at least two electrical conductors extending in parallel, that are held at a distance from each other and are insulated with respect to each other, the secondary winding being made up of part windings, which in each case are formed from one of the electrical conductors, each of the part windings, together with an associated capacitance, forming a series resonant circuit, whose resonant frequency corresponds substantially to the medium frequency of the primary current.
