Due to its special structure, it has the following characteristics: 1. Since all its components are made of non-combustible inorganic materials, the product is fireproof, flame-retardant, and does not produce toxic gases. Because the heating cable has a reliable metal tube seal and good grounding, it is especially suitable for various explosion-proof places. 2. Because the magnesium oxide insulation material remains stable even at temperatures up to 1800°C, the maximum operating temperature of the heating cable itself is the highest temperature that the core wire and metal outer sheath can withstand. 3. The insulation layer of the product, magnesium oxide, is an inorganic substance, and both the core wire and outer sheath are made of metal, which fundamentally solves the aging problem and greatly extends the service life of the heating cable. Under specified conditions, the service life can reach decades. 4. The product uses different outer sheaths that can resist oil, solvents, and most acids, providing good chemical stability. 5. Good mechanical properties: due to its robust structure, it can withstand twisting, squeezing, bending, pulling, friction, and general rough handling. 6. Since the heating method of this heating cable is a series resistance type electric heating element, the heating is uniform, and the temperature difference along the entire length is very small. 7. High heating power, generally above 30-60W/m. This heating cable does not risk freezing due to steam supply interruption like steam heating pipelines. It can be used by simply turning on the power when needed, without frequent maintenance. 8, low temperature resistance, not brittle at low temperatures, easy for winter construction and maintenance. 9. Resistant to solar radiation and nuclear radiation, with high operating temperature grades: 250°C, 400°C, 600°C, 800°C. Classification of MI Heating Cables Mineral insulated cables are cables that use metal (such as copper, copper-nickel alloy, etc.) as conductors, magnesium oxide mineral insulation as the insulator, and metal materials (such as copper, copper-nickel, stainless steel, alloy materials) as the sheath. If necessary, a plastic outer sheath or low-smoke halogen-free outer sheath can be extruded over the metal sheath. 1. Copper Sheath Mineral Insulated Heating Cable Can meet the needs of high-temperature conditions and long-distance pipeline heat tracing. Maximum withstand temperature up to 250°C; for applications requiring corrosion protection or burial, a high-density polyethylene HDPE outer sheath is needed, with a maximum withstand temperature up to 90°C; and has excellent mechanical strength. 2. Copper-Nickel Alloy Sheath Mineral Insulated Heating Cable The copper-nickel alloy sheath series mineral insulated heating cables can meet the needs of high-temperature conditions and long-distance pipeline heat tracing. Their maximum withstand temperature can reach 400°C; mineral insulated cables have excellent mechanical strength and corrosion resistance. 3. Stainless Steel Sheath Mineral Insulated Heating Cable The stainless steel sheath series mineral insulated heating cables can meet the needs of high-temperature conditions and high heating power (up to 269W/m). The maximum withstand temperature of this series of heating cables can reach 650°C; mineral insulated cables have excellent mechanical strength and corrosion resistance. 4. 825 Alloy Sheath Mineral Insulated Heating Cable The 825 alloy sheath series mineral insulated heating cables can meet the needs of high-temperature conditions and high heating power (up to 269W/m). The maximum withstand temperature of this series of heating cables can reach 800°C; the conductor resistance range from mineral insulated cables have excellent mechanical strength, high temperature resistance, and corrosion resistance, suitable for various explosion-proof places and special areas
