Product structure: the basic structure is a flat strip heating: electric wire spiral is placed on both sides of the center position of the metal protection tube, add flour with stentless automatic machine specially designed to high temperature insulation resistance, good thermal conductivity. High-purity magnesium oxide is uniformly filled into the protective tube, so do not send the displacement of electric wire, and then by the full continuous reduction of the machine since the protective tube pressed into flat, exhaust air between magnesium oxide powder, it will not only within the protective tube electric Silk is not oxidized, but also the heat transfer to the heating wire made object is heated while it has a large contact area, heating speed, high heat transfer efficiency, economical use of space, power, heating up fast, high reliability, heat capacity, long service life. Performance: Flat heating strip trusted by customers, with absolutely professional and excellent durability. High efficiency: After many years of research and development and practice to develop a high-precision flat heating strips. Heat generated by the flat heating strips can lossless conduction. Long life: the hotline using nichrome. Because Shi-like heat insulating oxide, the product has a longer life than ever before. Robustness: the outer protective tube stainless steel tube (GH3030). Withstand mechanical shock and vibration design is the result of long-tested and robust construction. Electrical properties: excellent electrical insulation, particularly at high temperatures can be maintained stable insulating properties. Operability: a plurality of heating rods simultaneously, it can be very coordinated without a hitch wiring. Variety: In order to meet the various needs of our customers, we have a variety of specifications. Technical parameters: sheath material: 1.USU304 2.USU321 3.310S 4.825 alloy, stainless steel and other insulating material: high-purity mineral magnesium Dimensions: section 13.5X5.5 (MM) maximum length: ≤50000M voltage: 220V or 380V ( specify when ordering) heating wire: a nickel-copper-nickel-chromium alloy 2. 3.PTC thermostat alloy Application:. ● ESP hopper wall insulation heating asphalt paver screed ● ● Preheat buried scraper conveyor ● dehydration machine warehouse doors heating insulation insulation insulation heating heating ● ● limestone bunker air delivery chute insulation heating heating ● ● electricity tower snow filling machine / roof packaging machines and other food machinery ● ● flat mold heating KFC, McDonald's, Keshi, Pizza oven and other kitchen equipment heated frying
