Flame Retardant 8MM Self-limiting Electric Heating Cable Solar Pipeline Antifreeze Self-Regulating Heat Trace Cable

Self regulating cables have an adaptable heat output and consist of two parallel bus wires embedded in a networked plastic heat element with surrounding carbon particles. If the temperature increases during operation, the plastic will expand and the distance between the carbon particles increases, resistance increases and output drops. When ambient temperature falls, this process is reversed and heat output increases – this is the principle of self regulation.
