Intelligent electric floor heating supply Baoshan | Baoshan high temperature high temperature heating cable AST EASTFIRE dual heating cable Intro: high temperature heating cable structure: 1, core: core wire having a positive temperature coefficient of resistance of the metal alloy wire composition, linear rated power of 18w / m. 2, the insulating layer: EASTFIRE heat insulation heating cable with double insulation structure, the insulating layer directly affects the quality of life of the heating cable, heating cable insulation temperature EST through trial and error, at 140 ℃ high temperature high temperature layer deformation, not shrinking. 3, grounding wire: ground wire from the 8 diameter of 0.4mm tinned copper lines. 8 tinned copper wire area of ??1.0048m square meters, in line with the provisions of the International Electrotechnical Commission IEC800 line shall not be less than 1m square grounding requirements. 4, a metal shield layer: in the course of the heating cable, since the current role in the electromagnetic field is formed around the heating cable, if more than 100 micro Tesla fields will be on human health and other electrical impact. Through the effective protection of the metal shield, the electromagnetic field within the core control line, so they can not spread out, and then by the electromagnetic field into the earth ground wire to make the heating cable and the earth formation potential. Through testing, EASTFIRE electric floor heating electric field strength generated value is within the scope of national security, 1/1000 (state of the electric field strength is 4000 volts / m, measured data EASTFIRE heating cable is 4 volts / m); magnetic induction the highest value was 13%, the lowest 6% (state of the magnetic induction intensity is 100 Witte Tesla, EASTFIRE electricity to warm up to 13 measured data Witt Tesla, Tesla minimum 6 Witt). Far below the national standard, higher than the national safety regulations, harmless, can be assured. 5, the outer sheath: PVC outer sheath for high-quality material. PVC has good anti-corrosion, anti-acid, anti-aging effects, and 100% waterproof. High-temperature heating cables related technical data 1, heating cable diameter: According to the State Administration of Quality Supervision, Inspection and Quarantine and the Standardization Administration of China in 2007 published "GB/T20841-2007IEC 60800:1992 rated voltage 300/500V living comfort heating and prevention Heating cables with icing "provides heating cable diameter not less than 6mm, EASTFIRE heating cable has a diameter of 6.5 ± 0.3mm, higher than the national standard. 2, heating cables linear power ─ 18W / m 3, the implicit connection: "EST" heating cable in the cold line hotline connection with the use of a proprietary patented welding method. Currently on the market most of the production of heating cable with cold connection method (cold, hot with mechanical crimping manner). In the long run, the heating part and the cold part of the contact point will lead to poor contact due to the formation of large resistance, high temperature part of the joint, the joint eventually burn out. Cold joints like a home furnace used as electric wire is rarely blown, and electric wire and power connectors often a problem. The "EST" implicit heating cable connector (a small-diameter wire docking method) method is patented heating wire welding with cold leads as one solution to solve the alternating hot and cold brought expansion and poor contact , to ensure that the heating cable cold leads, hot wire welding smooth transition, so that the heating cable at one go, leaving no blemishes; heating cables can be used to ensure the reliability, security, waterproof and resistant to mechanical external damage. Ensure that the service life of the heating cable. 4, heating cables logo: According to the State Administration of Quality Supervision, Inspection and Quarantine and the Standardization Administration of China in 2007 published "GB/T20841 ─ 2007/IEC 60800:1992 rated voltage 300/500V comfort heating and prevention of ice Heating cables" heating cables required surface markers legible, easily identifiable, rub resistance, signs spacing greater than 500mm, the most important is that the "EST" heating cable in cold joints, accurate way to identify with the marking on the cable in the heating, to warm the construction and testing to bring great convenience. Fourth, EASTFIRE high temperature heating cables related technical indicators: 1, high temperature indicators: Quality Supervision, Inspection and Quarantine and the Standardization Administration of China in 2007 published "GB/T20841-2007/IEC 60800:1992 rated voltage 300/500V comfort heating and prevention of ice Heating cables "provisions; heating cable core wire heating temperature up to 90 ℃, cable PVC jacket up to 65 ℃. And EASTFIRE temperature heating cable core wire heating temperature up to 100 ℃, PVC sheathed maximum temperature can be resistant to 90 ℃. EASTFIRE high temperature heating cables indicators are far higher than the national standard, and its meaning is: made with ordinary electric heating cable to warm above can not be used in its thick carpet or other floor coverings thereof as otherwise scattered due to temperature rise heating cable does not come out will cause malfunction, resulting in heating cable is not heating, and high-temperature heating cable EASTFIRE there is no such risk, EST's destructive test data are as follows: core wire 140 ℃, the carpet temperature of 100 ℃, carpet surface temperature 48 ℃. Carpet thickness is 10mm, test time 180 days * 24 hours non-stop, high temperature heating cable continues to work, while a control under the same conditions with a thick mulch of ordinary heating cable 11 days after the power has been damaged, the system is no longer Hot! Heating cable floor radiant heating system composition and working principle: power line transformer → → → low voltage distribution equipment household thermostat meter → → → heating cables radiate heat into the room through the floor a. To electricity for the energy b. To As a heating cable heating element c. heating cables heat conduction mechanism (a) heating cable after power it generates heat, its temperature at 40 ℃ -60 ℃, conduction through contact with heated enclosed in its weekly cement layer, and transmits it to the floor or magnetic brick, then heated air through convection, heat conduction heating cables accounted for 50% of the heat (2) The second part is energized heating cable will produce the most appropriate body 7-10 micron far infrared radiation to the human body and space . This part of the heat also accounted for 50% of heat, heating cable heating efficiency of nearly 100%. Heating cable inner core formed by the Cold Hot, outside the insulating layer, the shield and outer sheath component, the heating cable is energized, the hot heat and the temperature 40 ~ 60 ℃ runs embedded in the filling layer of the heat cable, heat by heat conduction (convection) the manner and sent 8-13μm far-infrared radiation heating pop.network body.
