Self-regulating heating cable KSTM

Hot pipe
Few conducting paths. Low heat output.
Warm pipe
Less conducting paths. Medium heat output.
Cold pipe
Many conducting paths. High heat output.
Self-regulating heating cable KSTM is a cable whose resistance varies with temperature – low resistance for temperatures below the cable set point and high resistance for temperatures above the cable set point. When the cable temperature reaches the set point the resistance goes high and then no more heat is supplied. This means heat is only supplied where needed along the length of the cable. Self-regulating heating cable KSTM consists of current carrying copper buswires of 0,5-1,0 mm2 cross section, semi-conductive self-limiting matrix, insulation, tinned copper braid and outer jacket. Outer jacket is made of the material resistant to ultraviolet and solar radiation, atmospheric precipitation and temperature differences that protects cable against moisture and mechanical damage. The self-regulating heating cable KSTM is designed to be used in electrical heating systems for domestic pipelines, drainage systems, roofs of buildings and constructions.
