Silicone electric heating film manufacturers introduce to you the introduction of precautions for the purchase of electric heating cables
Self-limiting temperature heating cable (self-regulating electric heating cable, self-limiting temperature heating cable) is the only new generation of belt-shaped constant temperature electric heater. The resistivity of the heating element has a very high positive temperature coefficient "PTC" (Postive Temperature Coefficent) and they are connected in parallel. The characteristics are: 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 cut arbitrarily or used in a certain length range, and allows multiple overlaps without any additional equipment. Concerns about high temperature, hot spots and burnout. These characteristics make the electric heat tracing have the advantages of preventing overheating, easy to use and maintain, and energy saving. It is suitable for temperature control, heat tracing, heat preservation, and heating of pipelines, equipment and containers, especially when materials are easily decomposed, deteriorated, crystallized, and frozen by condensation. It has a wide range of uses in petroleum, chemical, electric power, metallurgy, light industry, food, refrigeration, construction, gas, agricultural and sideline product production, processing and other sectors. The electric tracing cable is composed of nano-conductive carbon particles and two parallel busbars plus an insulating layer. Due to this parallel structure, all Jouze electric heating cables can be cut to any length on site and connected by two-way or three-way junction boxes. .
The self-control temperature heating cable is composed of a conductive polymer, two parallel metal wires and an insulating sheath. Its characteristic is that the conductive polymer has a high positive temperature coefficient characteristic, and they are connected in parallel, can automatically adjust the output power according to the temperature change of the heated system, automatically limit the heating temperature, and can be shortened or used in a certain range. , And allow multiple overlaps without high temperature hot spots and burnout.

In each heating cable, the number of circuits between the bus bars changes with the influence of temperature. When the temperature around the heating cable becomes cold, the conductive plastic produces micro-molecule contraction to connect the carbon particles to form a circuit, and the current flows through these circuits. Heat the heating tape.
When the temperature rises, the conductive plastic produces micro-molecule expansion, and the carbon particles gradually separate, causing the circuit to terminate, the resistance rises, 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, the carbon particles are connected to form a circuit, and the heating power of the heating tape automatically rises.
The self-limiting temperature heating cable has the advantages that other heating equipment does not have. The temperature controlled by it will not be too high or too low, because the temperature is automatically adjusted.
