Series Constant Wattage Polymer Insulated

Raychem-brand flexible series-resistance SC cables can be used when circuit lengths exceed the ratings of conventional parallel-resistance heating cables and a single power source is needed.

SC Cable Construction
Ohmic heating of the conductor provides the heat in this series circuit heating cable. Engineering design is necessary since the wattage output depends on the total circuit length and the voltage applied.
SC cables are available with one or two conductors for single phase or three phase systems. The resistance conductors are electrically isolated with high-temperature, heavy-wall fluoropolymers; a grounding braid; and a final fluoropolymer jacket.

SC Cable Performance
Maximum maintain temperatures to 250°F (121°C) and exposure temperatures of up to 482°F (250°C) are available. SC cables are capable of circuit lengths up to 12,000 feet with one power supply point and voltages up to 600 Vac.
