Introduction of self-limiting and low-temperature heating cables

Self-limiting temperature electric cable is also called self-regulating electric heating cable or self-controlling temperature electric heating belt. This is a ring-shaped temperature-limited heat tracer whose output power of electric heating is self-adjusted with the temperature of the system software. That is to say, the electric heating belt itself has the characteristics of automatic temperature limit, which can automatically adjust the heating power according to the temperature change of the heated system, so as to ensure the normal operation of the working system within the set working temperature range. The self-controlling electric heating tape can also be shortened or extended within the required range. It has excellent dielectric strength, aging resistance, bottom pressure operation, reliability, good flexibility, and is conducive to installation and application maintenance. Easy maintenance and other advantages.

Features of self-limiting and low-temperature heating cables

PTC effect, power self-regulation. The electric heating element of the automatic temperature control electric heating belt is a core belt made of PTC semiconductor heating material squeezed between two parallel wires. When the PTC core strip is energized, its resistance will automatically increase. When the temperature rises to a certain value, the resistance is large enough to almost block the current, and the PTC core temperature does not rise any more. At the same time, the PTC core belt transfers heat to the heated body through the sheath, and the temperature drops. At this time, the resistance of the core tape gradually decreases, and the heating temperature of the core tape increases again. This cycle keeps the temperature of the heating system constant so that it can perform well.
