Installation of Electric Heating Cable On Water Pipes

ELEKTRA Self-Regulating Heating Cable Technology


The capacity of heating cables to adjust their power output (heat) in response to temperature changes in their surroundings is known as self-regulation. The relationship between the temperature of the cable and the pipeline (water supply) is shown in the diagram. Following system activation, the heating cable “warms up” and increases power delivery while the pipe is still cold (blue) (red). The cable “cools down” and uses less power while the pipe is warmer.
