Patent ID: 7329814

Claim:
An electrical cable, comprising a first plurality of bundles located side-by-side adjacent to one another and each including a plurality of wires and connectable to a positive pole of a current source at one end; a second plurality of bundles located side-by-side adjacent to one another and each including a plurality of wires and connectable with a negative pole of the current source at one end; said bundles of said first plurality of bundles and said second plurality of bundles including bundles of same diameters, said wires in said bundles located side-by-side to one another having different diameters, and the wires of said bundles located side-by-side adjacent to one another are twisted in opposite directions so that the wires having a greater diameter of one bundle are twisted in one direction, while the wires having a smaller diameter of a neighboring bundle located side-by-side adjacent to said one bundle are twisted in an opposite direction, so that in one bundle of each of said plurality of bundles there are said wires of a greater diameter, while in another bundle of the same plurality of bundles located side-by-side adjacent to said one bundle there are said wires of a smaller diameter.
