Raychem self-regulating heating cables automatically adjust their power output to compensate for temperature changes. 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.
