Our self-regulating heating cables are made up of a semi-conductive matrix made of a mixture of graphite and polymer powder. It is extruded on two suitably cross-sectioned conductors as described in “cavi-autoregolanti” and “note-funzionamento-cavi-autoregolanti”.
Heat Trace has recently developed FailSafe technology which ensures that the cable temperature doesn’t rise above its maximum operating temperature. For these cables therefore, the maximum operating temperature is the same whether the cable is switched on or off.
The self-regulating nature of these cables render them very safe and reliable. They do not overheat or burn even if they are laid over each other and they do not require a thermostat to regulate the temperature.
For termination instructions in ATEX areas, see the original Heat Trace instructions for the relative kit.
