About Self-regulating heating Cables

Self-regulating heating cable has a modified-polyolefin outer jacket that ensures a long life - even when exposed to all weather conditions.  Simple-to-install, cable and tape can be cut-to-length and closely spaced without risk of overheating or burn-outs.

Self-regulating with adaptable output, various temperature range applications, demand-orientated output grading, high chemical resistance, no temperature limitation required, easy to lay and to install and can be cut to length off the roll.


Cold ambient: In response to cold, the core or fiber contracts microscopically opening up electrical paths.
Warm ambient: In response to warmth, the core or fiber begins to expand microscopically disrupting the electrical paths.
Hot ambient: The core or fiber expands enough to disrupt almost all of the electrical paths.

The outer jacket, braid and inner jacket provide mechanical, chemical and electrical protection... but the magic happens in the conductive core. The conductive core is extruded over the two, parallel conductors. As the ambient temperature drops, the core contracts microscopically and the number of electrical paths through the core increases. More heat is produced. Conversely, as the ambient temperature rises, the core expands and has fewer electrical paths. Less heat is produced.
A self-regulating heating cable adjusts its power output along its entire length. That’s what makes it a safe and reliable solution for many applications.
