Low temperature self-control electric heating belt

DST2-25Low temperature self-control electric heating beltSelf limiting temperature electric heat tracing has become a commonly used form of electric heat tracing in the world today, and is an advocated energy-saving and environmentally friendly product. Self limiting temperature electric heat tracing is widely used, including anti freezing protection for fire protection pipelines, industrial air conditioning water pipes, water treatment pipelines, industrial water pipelines, natural gas pipelines, and various tank containers; Heat tracing and temperature maintenance of various process pipelines and tanks such as oil pipelines, chemical pipelines, and edible oil pipelines.

Self limiting temperature electric heating strip (also known as self controlled temperature electric heating strip, self controlled temperature heating cable) is a new generation of strip constant temperature electric heating products. The resistivity of its heating element has a high positive temperature coefficient (PTC) and is connected in parallel. Its characteristics are: it can automatically limit the temperature during heating and automatically adjust the output power according to the temperature of the heating element without any additional equipment; It can be shortened arbitrarily or extended within a certain length range for use, and allows multiple cross overlaps without concerns of high temperature, overheating, or burning.

DST2-25Low temperature self-control electric heating beltWorking principle: In each electric heating strip, the number of circuits between busbars changes with the influence of temperature. When the temperature around the electric heating strip cools down, the conductive plastic shrinks, causing carbon particles to connect and form circuits. Current flows through these circuits, causing the electric heating strip to heat up.

When the temperature rises, the conductive plastic expands and the carbon particles gradually break, causing the circuit to be interrupted and the resistance to increase. The electric heating strip will automatically reduce power output.

When the surrounding temperature cools down, the plastic returns to its contracted state, and the carbon particles connect to form an electrical circuit. The heating power of the electric heating belt automatically increases again.
