The inner core of the heating cable is composed of a cold wire hot wire, and the outer core is composed of an insulating 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 transmits the heat energy to the heat receiver by means of heat conduction (convection) and 8-13um far-infrared radiation

Composition and working principle of heating cable ground radiation heating system: power supply line → transformer → low-voltage distribution device → household watt hour meter → temperature controller → heating cable → radiating heat indoors through the floor A. taking power as energy B. taking heating cable as heating body C. heat conduction mechanism of heating cable

(1) After the heating cable is electrified, it will heat up. Its temperature is 40 ℃ - 60 ℃, and it will heat the cement layer around it through contact conduction, and then transfer it to the floor or tile, and then heat the air through convection. The heat conduction accounts for 50% of the heat of the heating cable

(2) The second part is that when the heating cable is electrified, it will produce the most suitable far infrared ray of 7-10 μ m to radiate to human body and space. This part of heat also accounts for 50% of the heat, and the heating efficiency of the heating cable is nearly 100%.

The inner core of the heating cable is composed of a cold wire hot wire, and the outer core is composed of an insulating 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 low temperature of 40-60 ℃. The heating cable buried in the filling layer transmits the heat energy to the heat receiver by means of heat conduction (convection) and 8-13 μ m far-infrared radiation.
