Working Principle of Self-limiting Temperature Heating Belt
Features: It can automatically limit the temperature during heating and automatically adjust the output power according to the temperature of the heated body without any additional equipment; it can be arbitrarily shortened or extended within a certain length range, and allows multiple cross-overlapping without the worry of high temperature overheating and burning. These characteristics make electric heating have the advantages of preventing overheating, easy use and maintenance, and saving electricity. It is suitable for temperature control, heating, insulation, and heating of pipelines, equipment, and containers, especially when there are materials that are easy to decompose, deteriorate, crystallize, condense and freeze. It has a wide range of uses in petroleum, chemical, electric power, metallurgy, light industry, food, refrigeration, construction, gas, agricultural and sideline products production, processing and other departments. The
electric heating belt is composed of nano-conductive carbon particles and two parallel busbars with an insulating layer. Due to this parallel structure, all self-limiting temperature heating cables can be cut into any length on site and connected with two-way or three-way junction boxes.
In each heating cable, the number of circuits between the busbars changes with the influence of temperature. When the temperature around the heating cable becomes cold, the conductive plastic produces micro-molecular contraction and connects the carbon particles to form a circuit. The current passes through these circuits and makes the heating cable heat up.
When the temperature rises, the conductive plastic produces micro-molecular expansion, and the carbon particles gradually separate, causing the circuit to be interrupted, the resistance to rise, and the heating cable will automatically reduce the power output.
When the temperature becomes cold, the plastic returns to the state of micro-molecular contraction, and the carbon particles are connected accordingly to form a circuit, and the heating power of the heating cable automatically increases.
Self-limiting temperature heating cable has advantages that other heating equipment does not have. The temperature it controls will not be too high or too low because the temperature is automatically adjusted.
Classification of self-limiting temperature heating cable
Classification by application
Basic type electric heating cable: refers to a heating electric heating cable composed of copper wire, polymer PTC material and single-layer flame retardant sheath. It is mainly used for heating or heating of pipe networks in general occasions.
1. Tinned copper busbar 2. PTC heating element 3. Outer sheath
Explosion-proof electric heating cable: A layer of metal mesh is added to the outer layer of the basic electric heating cable. This type of electric heating cable can effectively eliminate static electricity and resist external mechanical collisions. It is mainly used in places with explosion-proof requirements.

Anti-corrosion and explosion-proof reinforced type: This type of heating cable is a composite layer of fluorine-containing material on the outer layer of the metal mesh of the explosion-proof heating heating cable. The heating cable with this structure can effectively prevent and resist static electricity, mechanical collision and various corrosive media. It is mainly used in places with harsh environments or flammable and explosive items.

The maintenance temperature of medium temperature heating belts is 110℃, and the tolerance temperature is 135℃. The maintenance temperature of high temperature heating belts is 135℃, and the tolerance temperature is 170℃.

each temperature range lists the main application occasions
Working principle of self-controlling electric heating cable
1. The self-controlling electric heating cable is composed of conductive plastic and two parallel busbars with an insulating layer. Due to this parallel parallel structure, all heating cables can be cut and connected at will on site (within a certain range), and the specified length shall not be exceeded.
2. The busbars in each heating cable are composed of conductive carbon particles. When the busbars are energized, the carbon particles form a circuit between the two busbars. The number of circuits varies with the influence of temperature. When the temperature around the heating cable becomes cold, the conductive plastic produces micro-molecular contraction and the carbon particles are connected to form a circuit. The current passes through these circuits and makes the heating cable heat up.
3. When the temperature rises, the conductive plastic produces micro-molecular expansion, and the carbon particles gradually separate, causing the circuit to be interrupted, the resistance to rise, and the heating cable will automatically reduce the power output.
4. When the temperature becomes cold, the plastic returns to the state of micro-molecular contraction, and the carbon particles are connected accordingly to form a circuit, and the heating power of the heating cable automatically increases.
5. The self-limiting heating cable has advantages that other heating equipment does not have. The temperature it controls will not be too high or too low because the temperature is automatically adjusted.
