A spirally wound Nickel Chromium or other type of resistance wire is then carefully wound the length of the cord. By varying the distance between contacts with the conductors, the number of turns per inch of resistance wire is then carefully wound the length of the cord. By varying the distance between contacts with the conductors, the number of turns per inch of resistance wire and the AWG size (resistance) of the spirally wound wire, different wattages per foot per service voltage can be obtained. A third conductor may be placed parallel to the assembly described above. Heating Element - Nickel Chromium, copper alloy or other suitable resistance wire is spirally wound around the insulation; the AWG size of wire, number of turns, length between contact with the copper conductor are dependent upon the wattage demand and the voltage used to energize the cable.
