The Classification and Working Principle of Self-regulating Cable

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

Classification

Self-controlling electric heating cable, also known as self-controlling electric heating cable, is a new generation of constant temperature electric heating cable. The positive temperature coefficients are high 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 measured body. Can be cut arbitrarily or extended within a certain length. Easy maintenance and energy saving.

Working principle

Self-limiting electric heating cables work on the principle that when the temperature around the heating cable cools, the conductive plastic in each heating cable shrinks and the carbon particles connect to each other to form an electrical 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 to increase, and the electric heating cable will automatically reduce the power output. When the ambient temperature becomes cold, the plastic returns to a shrinking state, the carbon particles connect to form a circuit, and the power of the electric heating cable automatically rises.

The self-regulating heating cable has a uniform temperature, will not overheat, and is safe and reliable. Save power, heat up quickly, and start quickly. Low installation and running costs and easy installation and maintenance. Widely used in fire-fighting pipes, industrial air-conditioning water pipes, water treatment pipes. It can also carry out heat tracing and process insulation for various process pipelines and tanks.
