Overview of Self-limiting Electric Heat Tracing Cable
Self-limiting electric heat tracing cable, also known as self-regulating electric heat tracing cable, is a new generation of the only带状 constant temperature electric heating product. It is composed of polymer 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-limiting Electric Heat Tracing Cable
Self-limiting 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-overlapping without the risk of overheating and burning. It is easy to maintain and saves energy.
