ABSTRACT:
A three-conductor cable (10) including three stranded electric cables (1), each having a core that has a current conductor (2) and a neutral and/or return conductor. Each individual cable (1) is essentially characterized in that the neutral and/or return conductor is configured from a number of individual conductors (4), distributed concentrically around the current conductor (2), that an insulating sheath (3) is provided between the current conductor (2) an the distributed individual conductors (4) of the neutral and/or return conductor and that a protective jacket covers the neutral and/or return conductor.
