Abstract
The heavy current cable (1) for 50/60 Hz TN-S mains comprises preferably a central earth connector (2), around which three phase leads (3, 4, 5) and a neutral lead (6) are stranded. The earth lead (2) can have a smaller cross-section than the phase leads (3, 4, 5) and the neutral lead (6), and can be straight. This heavy current cable (1) is characterised by a defined cable reactance, by a constant current distribution over the phase cables and by the avoidance of any induction currents. In addition virtually no interference can be coupled into parallel lying I & C-leads. There is only a low level of NIS-radiation and no short-circuiting forces. Finally, there is a time saving during installation.
Claims6
Three-phase heavy current cable for 50/60 Hz TN-S mains, comprising at least one ground conductor, around which are stranded at least one neutral conductor and a three-phase current conducting element consisting of three phase conductors, and wherein the ground conductor has a smaller cross section than the phase conductors and/or the neutral conductor.
