How to choose the right electric heating cable?

1. Raw material: The self-controlled temperature electric heating cable is composed of two kinds of sheaths (fluorine plastic jacket and PVC sheath). The constant power parallel electric heating cable has only the outer sheath of the fluorine-containing raw material and the shielding network layer with the tropical structure. .

2. Maintaining temperature: The self-controlled temperature heating cable can keep the temperature range between 65 degrees and 105 degrees. The maximum power of the constant power parallel electric heating cable can reach 180°, and the temperature belongs to the high temperature range.

3. Application length: The longest single root length of self-control electric heating cable should be controlled within 100m. The insulation effect beyond this range can not be guaranteed, the effect can not be expected; the longest single power of constant power parallel electric heating cable can reach 250 meters, The above self-control temperature is longer, used in long-distance pipelines, and the power supply junction box can be extended to extend the insulation range.

4. Ribbon width: The self-controlled temperature heating cable has a widened core band of 13 mm, while the constant power parallel electric heating cable cannot exceed 8 mm.

5. Wire core standard: The self-controlled temperature electric heating cable diameter is 7*0.42 and 7*0.5 and 19*0.25.

6. Voltage requirements: self-controlled temperature electric heating cable 380V power maximum 35W, constant power parallel electric heating cable 380V maximum power 30W

In real life, there are still many users who are not very familiar with the electric heating cable. They often entangled in whether they should choose to use constant power electric heating or self-limiting thermoelectric heating in certain situations. The material and working principle of constant power electric heating cable and self-controlled temperature heating cable are different. The materials, temperature maintenance, length of use, etc. are all different. When selecting, you must choose the configuration according to the actual situation. Constant power electric heating and self-limiting temperature electric heating can also be used when necessary.
