Self-regulating Cable technology
Self-Regulating cables can be used for applications such as freeze protection and process temperature maintenance on long lines heating systems. Depending on cable choice, self-regulating cables can withstand continuous exposure temperatures to 300°F (150°C), intermittent exposures to 420°F (215°C) with maximum circuit lengths of up to 12,000 feet (3660m).

Mineral insulated heating technology
Pyrotenax ® brand mineral insulated heating cables are used in longline applications where high temperature maintain and/or high temperature exposures exist, or high power output is required. MI heating cable is used in many applications, including transfer lines. It is rugged and economical, and can be used for lines up to 5000 + feet (1500 + m). A 600 Vac Delta or Wye electrical configuration balances the electrical load well. Designs must be done on a case-by-case basis because the total resistance must be matched to the transformer characteristics.

Series-resistance heating technology
Raychem brand flexible series-resistance heating cables can be used when circuit lengths exceed the ratings of conventional parallel-resistance heating cables and a single power source is needed. Ohmic heating of the conductor provides the heat in this series circuit heating cable. Engineering design by Tyco Thermal Controls is required since the wattage output depends on the total circuit length and the voltage applied.
SC cables are available in single- and double-conductor configurations for single- or threephase system design. The resistance conductors are electrically isolated with high-temperature, heavy-wall fluoropolymers; a grounding braid; and a final fluoropolymer jacket. 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 10,000 feet (3048 m) with one power supply point, and voltages up to 600 Vac.
