MI Heating Cable
MI heating cables are most suitable for high maintenance temperature in-plant piping/tank application. Mineral Insulated heating cable is a constant wattage Series circuit cable and is constructed of a run of specific-low resistance solid wire(s), insulated with Magnesium Oxide and finally covered with a metallic protective jacket. The figure illustrates the construction of a single conductor MI heating cable. These are factory terminated cables in the required specific lengths and cannot be spliced in the field.
