Overview of Self-Regulating Electric Heat Tracing Cable
Self-regulating electric heat tracing cable, also known as self-controlling electric heat tracing cable, is a new generation of the only constant-temperature strip heating product. It consists of high-molecular conductive carbon particles, two parallel bus wires, and an outer insulation layer. The PTC heating element has a high positive temperature coefficient of resistivity and is connected in parallel.
Features of Self-Regulating Electric Heat Tracing Cable
Self-regulating electric heat tracing cable can automatically limit the heating temperature and adjust the output power according to the temperature of the traced object. It can be cut arbitrarily or extended within a certain length. It allows multiple cross-overlaps without the risk of overheating and burning. It is easy to maintain and saves electrical energy.
