The function and selection skills of heating cables

A heating cable consists of a cold wire, a hot wire, and a cold hot wire joint, with the structure consisting of a heating wire, insulation layer, grounding shielding layer, and outer sheath.
Working principle of heating cable:

The core of the heating cable is composed of a cold wire and a hot wire, and the outside is composed of an insulation layer, a grounding layer, a shielding layer, and an outer sheath. After the heating cable is powered on, the hot wire heats up and operates at a temperature of 40-60 ℃. The heating cable buried in the filling layer transfers thermal energy to the heat receiving body through thermal conduction (convection) and the emitted 8-13um far-infrared radiation

The function of heating cable:
The reason why heating cable heating is called the most ideal heating method in winter is not only because of its economy, safety, convenience, and high quality, but also because it regards people as the main body of life, highlighting the three modern life themes of comfort, health, and environmental protection; Highly humanized design, simple and flexible control methods, bring great convenience to users; The system structure hidden underground maximizes the saving of indoor space.

Tips for selecting heating cables:
1、 Look for a smooth and even appearance; Not to mention the specifications, models, resistors, etc. on the cable, if the words are sprayed on by the machine, there will be dark patterns similar to Braille.

2、 Structurally, from the inside out, there are: carbon fiber thread (24k or 12k) - F46 PTFE - polyvinyl chloride PVC sheath.

3、 Looking at the connectors, this is also a technical challenge for heating cables. At present, the imported cables mainly consist of joints that have been injection molded once, with mature technology and good reliability, resulting in relatively improved stability and water resistance.

Heating cables will become increasingly common in daily life, so it is necessary for everyone to understand the selection of heating cables.

The advantages of heating cables are mature technology, long service life, stable performance, and their application history of over 50 years is still in use abroad.
