High Temperature Mineral Insulated MI Heating Cable For Valves / Flanges

(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.
