Introduction to the classification principle of self-regulating heating cables

Self-regulating heating cables have become the most common form of electric tracing cables in the world today, and are energy-saving and environmentally friendly products advocated by the state. 

Its characteristic is that it can automatically limit the temperature when heating, and automatically adjust the output power according to the temperature of the heat-traced body without any additional equipment.

It can be arbitrarily cut or extended within a certain length range, and it is allowed to overlap and overlap multiple times. No high-temperature hot spots and burning concerns.

Classification

Self-regulating heating cable, also known as self-controlling temperature electric heating cable, is a new generation of constant temperature electric heating products. 

High positive temperature coefficient and parallel to each other. 

The self-regulating heating cable can automatically limit the heating temperature and automatically adjust the output power according to the temperature of the traced body. 

It can be cut arbitrarily or extended within a certain length range. Easy maintenance and energy saving.

The Working Principle

The working principle of the self-limiting electric heating cable is that in each heating cable when the temperature around the heating cable becomes cold, the conductive plastic shrinks, and the carbon particles are connected to form a circuit. fever. 

When the temperature rises, the conductive plastic expands and the carbon particles are gradually disconnected, causing the circuit to be interrupted, the resistance increases, and the electric heating cable will automatically reduce the power output. 

When the surrounding temperature becomes cold, the plastic returns to its shrinking state, the carbon particles are connected to form a circuit, and the power of the electric heating cable automatically rise.

The self-regulating heating cable has a uniform temperature, will not overheat, safe and reliable. It saves electric energy, fast heating, and start-up. 

Low installation and operating costs, easy installation, and maintenance. It is widely used in fire pipelines, industrial air conditioning water pipes, and water treatment pipes. And it can heat tracing and process temperature maintenance for various process pipelines and tanks.
