Features of carbon fiber infrared heat lamps

  1. High electrothermal conversion efficiency and significant energy-saving effect The carbon fiber heating element is a pure black body material. During the electric-heat conversion process, the visible light is very small, and the electric-heat conversion efficiency is more than 95%. Compared with nickel-chromium, tungsten-molybdenum and other materials as heaters, it can save energy by 30%; Under the same power, the radiation temperature of the carbon fiber heating tube is 30℃ higher than that of the nickel-chromium metal electric heating tube and 15℃ higher than that of the tungsten molybdenum wire quartz electric heating tube. 2. No instant current impact The ignition does not require a ballast, and there is no pulse current impact when starting, which simplifies the lighting power supply and protection circuit, and prolongs the service life of the power supply and related electrical appliances. 3. The high heat radiation direction can improve the design of directional heat radia

The wiring method of infrared heating tube

  1\ The infrared heating tube is a resistance heating tube. When connecting to DC power, there is no distinction between positive and negative poles. When the rated voltage is 220V, the heating tube is connected to 220V AC. The 220V connection method is also called "Star connection". First divide the heating tubes into three groups of equal number, then connect one end of the three groups of heating tubes to a common point, and then connect the other ends of the three groups of heating tubes to the three power lines of the three-phase power supply. Protective measures. This process must ensure that the power and quantity of the three sets of heating tubes are the same. Otherwise, the center store will shift and the heating tube will be burnt out. 2\ When the heating tube is connected to 380V industrial power, the voltage and the zero line must be confirmed first. It should be noted that if the rated voltage of the heating tube is confused, the heating tube will burn out or t
