Multiple-phase electrical system

An electrical system comprising:

• a multiple-phase electrical power source having at least three phases, the phases having phase voltages of substantially equal magnitude and substantially equal angular spacing;
• a multiple-phase electrical load having a number of phases equal to the number of phases of the multiple-phase power source and which presents a substantially equal electrical load on each phase;
• and
• a cable for transferring power from the power source to the load, the cable further comprising:
• a center conductor with a cross-sectional area, the cross-sectional area being sufficient to carry the current drawn by the load on one phase of said power source;
• a number of additional conductors disposed about the center conductor, the total number of conductors including the center conductor being equal to the number of phases of said multiple-phase electrical power source, said additional conductors each having a cross-sectional area sufficient to carry the current drawn by the load on one phase of said power source;
• a number of insulators, each insulator disposed between two conductors, each insulator further being of sufficient thickness to substantially prevent current flow between the two conductors between which the insulator is disposed;
• and
• an insulating jacket disposed around all of the conductors and insulators;
• wherein each conductor of said cable is electrically connected to one phase of the multiple-phase electrical power source and one phase of the load, whereby electrical power is transferred from the power source to the load.
