1. A cable comprising:
an inner conductor having a first direct current resistance and a first cross-sectional area between that of a 4 AWG and a 6 AWG wire, the inner conductor formed from a first plurality of uninsulated conductive elements helically stranded together;
an outer conductor coaxially arranged around the inner conductor, the outer conductor having a second direct current resistance approximately equal to the first direct current resistance such that the inner conductor and the outer conductor comprise a balanced pair of conductors;
a first dielectric layer comprising polyvinylchloride positioned between the inner conductor and the outer conductor;
a second dielectric layer comprising polyvinylchloride positioned around the outer conductor; and
a third dielectric layer comprising nylon positioned around the second dielectric layer,
wherein the outer conductor is formed from a second plurality of uninsulated conductive elements helically stranded around the first dielectric layer, each of the second plurality of conductive elements comprising a second cross-sectional area of at least 0.5 square millimeters.
