ABSTRACT:
A multi-strand electrical cable having electrically conductive strands of different cross-sections, i.e. cross-sectional areas, arranged in ascending order of strand cross-section from the center toward the outer circumference of the cable and sized in accordance with an irrational and preferably golden ratio progression in such a way that larger strands are located outwardly toward the cable circumference relative to smaller strans and stabilize the smaller strands against resonant vibration in a manner such as to reduce cable resonance produced by fluctuating current flow through the cable.
