Abstract :
Cable installations for three-phase systems consisting of parallel single-core cable circuits carry different currents due to inductive coupling. Supplementary installed additional conductors grounded on both ends show several beneficial effects: balanced outer conductor currents, improved throughput load, and reduced current-dependent losses. With cables laid in free air, additional conductors are especially economical
