Electric heating cable

Self-regulating electric heating cable comprises two wires embedded in a semiconductor self-regulating matrix. It means that the cable automatically reacts to external conditions. When the temperature rises, the synthetic materials expands at the molecular level. The bonds between carbon atoms weaken and reduce electric resistance, whereas when the temperature decrease, molecular bonds become strengthened, thus leading to resistance increase. Thus, the heating power changes proportionally to the cable surface temperature. The self-regulating heating cable does not overheat or burn even in places in which two cable sections contact each other.

The self-regulating heating cable is used in the TERMOTECH Termoplasty systems in the following cases:

  • anti-freezing function - the thermostatic devices has set constant temperature, e.g. +5.0oC

  • constant temperature maintenance function for the pumped agent


The cables in a certified version are also available Ex - explosion-safe design.

To obtain elements with a heating cable, upon placing an order, please enter KG in the OPCJA field in the order form together with target setpoint temperature, e.g. +5oC.
