Self-limiting electric heat tracing overview

Self-limiting temperature electric heating tape, also known as self-regulating temperature electric heating tape, is a new generation of strip-shaped constant temperature electric heating product. It is composed of high polymer conductive carbon particles, two parallel busbars, and an insulating layer. The resistance rate of its PTC heating element has a high positive temperature coefficient and is connected in parallel.

Self-limiting temperature electric heating tape features

Self-limiting heat tracing cables can automatically regulate the heating temperature and adjust the output power according to the temperature of the heated object; they can be cut to any length or extended within a certain range; they allow multiple crossings without the risk of overheating and burning; they are easy to maintain and energy-efficient.
