1. A cable configured for high current applications, the cable comprising:
a conducting member comprising a first conductor, a second conductor, and a third conductor, wherein the first conductor, the second conductor, and the third conductor are surrounded by a single insulating layer;
a cooling conduit comprising a tubular portion and a coolant, the coolant configured to flow within the tubular portion to cool the conductor; and
wherein the conducting member is spiral wound around the cooling conduit along a length of the cooling conduit to increase a contact area between the conducting member and the cooling conduit to thereby improve a transfer of heat from the conducting member to the cooling conduit.
