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带状恒温 electric heating product. It is composed of polymer conductive carbon particles and two parallel bus wires plus an insulating layer. The resistivity of its PTC heating element has a high positive temperature coefficient and they are 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 range. It allows multiple cross overlaps without the risk of high temperature 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 insulating layer
④ Metal shielding layer (tinned copper wire or aluminum-magnesium alloy wire)
