Overview of Self-Regulating Electric Heat Tracing Cable
Self-regulating electric heat tracing cable, also known as self-controlled electric heat tracing cable, is a new generation of the only strip-shaped constant temperature electric heating product. It is composed of polymer conductive carbon particles, two parallel bus wires, and an insulating layer. The resistivity of its PTC heating element has a high positive temperature coefficient 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 overlaps without risk of overheating and burnout; it is easy to maintain and saves electricity.
Structure of Low Temperature Protective Electric Heat Tracing Cable
① Tinned soft copper conductor
② PTC fluoropolymer core tape (heating layer)
③ Perfluoro F46 insulation layer
④ Metal shielding layer (tinned copper wire or aluminum-magnesium alloy wire)
