(MI) Mineral Insulated Heating Cables
MI Cable is Mineral Insulated semi-rigid electric resistance wire heating cable. The resistance wire heating element is electrically insulated using Magnesium Oxide (Mineral) to ensure safe electrical insulation with maximum thermal transfer. The mineral insulation is then encapsulated in a metal sheath for extreme durability and environmental protection. MI cable is a durable and long lasting heating cable that is capable of heating to very high temperatures. MI cable can be used in both ordinary and hazardous locations/areas and is versatile enough that it can be used for a wide range of surface heating and radiant heating applications.
Structure:
| No. | structure | Material | Function |
| 1 | Single or multiple conductors | NiCr80/20, Copper, CuNi23, Constantan | Heating elements |
| 2 | First insulation | Magnesium oxide insulation | Mgo provides insulation of the resistance wire for voltage up to 593℃. |
| 3 | Inner jacket | Metal sheath (Copper, SS310, SS316, SS321, Inconel 600, Inconel 625) | This alloy has excellent resistance to pitting , chloride-stress, acid and alkali corrosion. |
| 4 | Outer jacket | High-density polyethylene jacket | For corrosive environments or extra ruggedness when embedded in concrete. |
Custom made units as per exact requirements.
