Self-Regulating Heat Trace
The self-regulating cables are the most common in current projects and provide temperature control of the process piping.
The self-regulating cables have a semiconductor matrix in the core, which as the temperature decreases, contracts, forming several electrical paths (resistances) between the conductors “A” and “B”, allowing the current to pass between them and generating Heat, conversely, when the temperature drops, this core expands, the resistance tends to infinity, and no longer passes electric current, thus ceasing heat generation.
Self-regulating cables are used for process piping maintenance temperature up to 149°C and maximum intermittent exposure of 232°C, which is a limitation of self-adjusting cables.
