3M Architecture & Construction : 3M™ KSR™ Self-Regulating Heating Cable

Properties:

The Heat Tracing Cable consists of a conductive-polymer heating matrix extruded between two parallel copper bus conductors. Heat is generated in the conductive polymer matrix when energized. The bus conductors provide uniform voltage across the heating matrix by providing current down the entire length of the cable. The conductive polymer matrix is irradiated with an electron beam to provide cross-linking and “lock in” performance properties.

As the temperature increases, the electrical paths in the carbon-polymer heating matrix become longer and the resistance of the heating element increases. This causes the heat output of the cable to decrease. As the temperature of the heating matrix increases, the resistance of the heating matrix increases. This is a self-regulating effect.

Self-regulating Heat Tracing Cables can adjust their output to the surrounding temperature down the cable length. This adaptability to individual thermal conditions provides more heat where needed and can also reduce energy consumption as the ambient temperature increases, reducing heating costs.
