230V Twin conductor heating cable units 10W/m

Heating cable, is made of cable structure, electricity as an energy source, the use of alloy resistance wire or carbon fiber heating body far infrared for electrification heat, known as carbon fiber heating cable or carbon fiber hot line, used for electric underfloor heating system, also known as carbon fiber underfloor heating, to achieve the effect of heating or heat preservation. The use of alloy resistance wire, known as heating cable, heating cable, metal heating cable, the purpose of which is used to heat, its use is for living facilities heating and anti-icing heating cable.

The working principle of heating cable:

The inner core of the heating cable consists of a cold wire hot line, the outside by the insulation layer, grounding, shielding and outer sheath, the heating cable is energized, the hot line heats up and operates between the temperature of 40 to 60 ℃, buried in the filling layer of the heating cable, the heat will be transmitted to the recipient of the heat by means of heat conduction (convection) and the emission of the 8-13 um of far-infrared radiation.

Composition and working flow of heating cable floor radiation heating system:

Power supply line → transformer → low-voltage distribution device → household meter → thermostat → heating cable → through the floor to the indoor radiation of heat

a. Electricity as energy source

b. heating cable as a heat generator

c. Heat cable heat conduction mechanism

(1) the heating cable will heat up when it is energized, its temperature is 40℃-60℃, through contact conduction, heating the cement layer surrounded by its circumference, and then to the floor or tiles, and then through convection to heat up the air, the conduction heat accounts for 50% of the heat generated by the heating cable.

(2) The second part of the heating cable will produce the most suitable 7-10 micron far infrared rays when it is energized, radiating to the human body and space. This part of the heat also accounts for 50% of the heat, heating cable heating efficiency is nearly 100%.

After the heating cable is energized, the hot line composed of nickel alloy metal inside is heated and operates at a low temperature of 40-60°C. The heating cable buried in the filler layer will transfer heat to the heated body by means of heat conduction (convection) and emission of 8-13 μm far infrared rays in a radiant manner.
