Chromalox MI mineral insulated heating cables provide rugged and reliable heat tracing for a variety of demanding applications. The high nickel alloy sheath, magnesium oxide dielectric insulation and resistance wire construction allow the tracing of equipment up to 1100°F maintenance temperatures and excellent resistance to many corrosive environments. At lower temperatures, watt densities of up to 50 W/Ft can be designed. Please contact factory for cable maintenance temperature above 400°F.

Construction

A. Metal Sheath: High nickel content Alloy 825 is recognized for its use in high-temperature applications, and use in many corrosive environments. This alloy has excellent resistance to pitting, chloride stress, acid, and alkali corrosion. Stainless steel is also available.

B. MgO: Highly compacted Magnesium Oxide provides insulation of the resistance wire for voltages up to 600V. Completely sealed sheath protects the MgO from moisture & contamination.

C. Resistance Wire: A large number of available resistances enables the design of a large range of lengths and wattages. Double and single conductor available.

D. Cold-Lead (Shown Below): Non-heating MI cable extends the leads away from the high-temperature equipment. 4 ft. long is standard.

E. Gland Fitting (Shown Below): Every set includes one or two 1/2” NPT fittings for connection to a junction box. The number of fittings depends on the configuration of the cable set. (Optional 3/4″ NPT)
