Anjou Boutique (AR) with a three-phase constant power electric band (RDP-J3), GWDRD electric heating ..

Product Name: Three-phase electric power with constant belt Model: RDP3-J3-30 RDP3-J3 (Q) -40 Usage: pipe with heat, auxiliary insulation Product description: The principle of three-phase constant power heating cable is basically the same, different The place is a single-phase power supply with single-phase, three-phase three-phase delta constant wattage power supply, three-phase single-phase with the addition to the characteristics of the heating cable, it is particularly suitable for long-distance, large-diameter pipe heat tracing and insulation It can be used to plant an area, two areas T3 group explosive gas mixtures occasion. First, the model meaning: Second, the product structure and working principle: three parallel insulated copper wire for the power bus, including the sheath electric wire wound on the insulating layer, and (that is, "eagerly long hair") electric wire at a certain distance followed by repeated cycles are connected to the power supply bus AB-BC-CA-AB ......, in every two phases form a continuous parallel resistance. When the generatrix is ??connected to three-phase power, while the parallel resistance heating, thereby forming a continuous three-phase power plus tropical. Product specifications and main technical characteristics of the product model rated power (w / m) Maximum length (m) fluid maintain the highest temperature (℃) (internal) outer sheath color Normal enhanced RDP3-J3-10 RDP3 (Q) -J3 -10 30 330 120 ℃ blue RDP3-J3-20 RDP3 (Q) -J3-20 40 280 110 ℃ orange RDP3-J3-30 RDP3 (Q) -J3-30 50 275 80 ℃ red RDP3-J3-40 RDP3 (Q) -J3-40 60 250 60 ℃ black fluid maintain the highest temperature: refers to the need to maintain the pipeline medium maximum process temperature, generally should not exceed the values ??specified in Table Rated voltage: 380V maximum temperature: 205 ℃ normal insulation resistance : ≥20 megohms protection: IP54 Dielectric strength: 2500V 50Hz / 1min Certificate of Conformity: CJE × 07.125U Insulation Material: F46 fluorine plastic Dimensions (including textiles and outer sheath): 12 × 6.3mm Third, the product Features: Three-phase constant power heating cable in addition to a single-phase constant power heating cable the same characteristics, has the following advantages: 1, three-phase band higher than the maximum permitted length of the single-phase heating cable 2, large-scale application in power Tropical occasions, can balance the network load 3, three-phase heating cable thanks to three core wires, so that more flat band, reducing the surface of the heat load, increase the heat transfer area of ??the pipeline to improve the heat transfer efficiency of the heating cable and the highest maintaining the temperature. Fourth, product applications: This band is suitable for piping, valves, heating pump, the freeze protection and temperature meter pipes or maintain process temperatures, especially for large caliber, long-distance heating insulation. (1) Under normal circumstances, a continuous flow of low freezing line use, to avoid the media due to stop the flow and solidification. (2) the need to strictly control the operating temperature of the liquid line of heating and insulation. (3) the cold zone in the water pipelines and valves antifreeze, drain suction pipe and condensate lines antifreeze. Antifreeze (4) Offshore pipelines. (5) The general heating insulation pipes and instruments. (6) Wellhead oil heating shaft (replace water jacket), water wells with heat. (7) the runway anti-ice frozen. (8) concrete products, antifreeze conservation
