A conductor arrangement 90 for inductive power transfer comprises at least three coils 1a, 1b, 1c, arranged along a longitudinal axis LO and formed of at least one conductor. The conductor arrangement comprises at least two winding heads W arranged opposite to one another and in which conductor sections of each of the coils 92, 94 extend along one another as well as along the longitudinal axis. Within at least one of the two winding heads, the conductor sections of a first and second coil 92 that extend along the longitudinal axis are arranged at a first distance to one another. The conductor section of the third coil 94 that extends along the longitudinal axis is arranged at a second distance to the conductor sections of the first and second coil, the second distance being larger than the first distance. In an alternative arrangement a magnetisable material is placed between at least two of the conductor sections within at least one of the winding heads. The arrangement may be used to inductively charge an electric vehicle 4.
