Abstract: The three-phase overhead cable has return conductors (7-9) beneath each of the three phase conductors (L1-L3) for connection of components (1-3) of the source, e.g. transformer windings or generators, and/or components (4-6) of the sink, e.g. transformer windings or loads. Counter currents flowing in the return conductors have the same amplitude as, but opposite phase to, the phase currents flowing in the corresp. phase cables.
