The main features of MI single and double conductor high temperature heating cables and heating systems:

MI cable mineral insulated high-temperature heating cable has a long service life, is not easy to age, and has high compressive strength because its structure is inorganic. Because its outer sheath is a metal sheath, it determines that it will not age for a long time and can be used in Long-term operation at high temperatures. Therefore, MI cable mineral insulated high temperature heating cable has absolute advantages.

1. Fire protection: MI cable mineral insulated high-temperature heating cables are made of non-polar materials, which makes it impossible for the cable to burn, let alone support combustion or release toxic and harmful gases at high temperatures.
2. Explosion-proof: MI cable mineral insulated high-temperature heating cable is a solid structure composed of seamless metal sheath and tightly compacted mineral insulating material, which fundamentally prevents the intrusion of flammable gases and flames, and is a true explosion-proof cable . .
3. Anti-corrosion: The sheath of MI cable mineral insulated high-temperature heating cable is a seamless metal sheath. When selecting, a suitable metal outer sheath can be selected according to the actual conditions of the workplace, which fundamentally avoids corrosion of the cable.
4. Anti-penetration: The sheath of MI Cable mineral insulated high-temperature heating cable is a seamless metal sheath, so neither liquid nor gas can penetrate into the interior of the cable.
5. Radiation protection: MI cable mineral insulated high-temperature heating cables are made of non-polar materials, so the performance indicators of the cable will not change when working in places with radiation.
6. Long life: The characteristics of the materials of MI cable mineral insulated high-temperature heating cables determine that the cable does not have the problem of insulation aging and has long-term stability.
7. Good flexibility: MI Cable mineral insulated high-temperature heating cable has been softened before leaving the factory, has excellent flexibility and can be bent freely. It can be laid in narrow spaces and irregular-shaped equipment, which provides great convenience for installation and construction, and the lines are beautiful after installation.
8. High mechanical strength: Due to the inherent characteristics of the structure of MI cable mineral insulated high-temperature heating cables, the cables can withstand severe mechanical damage and can still work normally when the cable diameter is deformed by one-third.
9. Because the heating method of this cable is a resistive electric heating element connected in series, the heating is uniform and the temperature difference along the entire length is extremely small.
10. The heating power is large, generally above 50W/m. This cable does not have the risk of freezing due to the stoppage of steam supply like steam heating pipelines. The power can be turned on when needed and does not require frequent maintenance.
11. It is resistant to low temperatures and will not break when constructed at low temperatures, making it easy to construct and maintain in winter.
12. Low project cost: MI cable mineral insulated high-temperature heating cable is small in size, so the amount of insulation material will not be increased when laying, and the boiler and water treatment system for steam and water heating are omitted, and the construction is convenient and fast. This directly reduces the cost of the project.
13． Low operating costs: The heating system composed of MI cable mineral insulated high-temperature heating cables can be controlled remotely, remotely and automatically, and can ensure accurate and timely supply of the heat required by the heated object through the temperature control part, so there is no additional heat losses and redundant operating personnel, Guaranteed very low running costs .
14. Low maintenance costs: The heating system composed of MI cable mineral insulated high-temperature heating cables has a simple structure, long life, and high reliability, which reduces the components and time required for maintenance. It can even be used normally without maintenance in places where the working environment is not particularly harsh.
