Abstract

A heating cable includes at least a pair of elongated electrode wires, each of which is coated with a first layer of insulating material that is at least partially stripped off said wires at spaced, alternating locations. A resistive heater wire is spirally wound around a core of insulating material, to form an elongated resistor core. The elongated resistor core is spirally wound around the electrode wires whereby the heater wire is brought into electrical contact with the electrode wire at the alternating locations, to electrically connect same with the resistive heater wire. A second layer of an insulating material is provided over the resistor core and forms an outer surface for the cable.
