Heat is generated by current flowing through a nichrome, copper, or other metal conductor, insulated with magnesium oxide and encapsulated in an outer metallic sheath of copper, stainless steel, Inconel, or other suitable metals (see picture right).

MI cable is capable of carrying high heating loads. Given the proper conductor and sheath alloys, it can be used in applications up to 800°C. Its high impact resistance and general ruggedness allows it to stand up to rough handling in the field. Circuits usually are factory fabricated to length prior to installation, which can be a source of problems when piping changes are made since installations are difficult to field modify.

MI Cables have excellent mechanical strength and are non-combustible. They are series resistance heaters which must be designed to provide the required heat output.

>> High performance output
>> Wide temperature range
>> Fire resistant
>> High mechanical resistance

The high temperature capabilities may be required for the following typical applications:

Nuclear Industry - Sodium loops
Building Industry - Bitumen / asphalt heating
Metal Forming Industry - Melting of low melt alloys

The ability to be easily formed into shapes is useful for tank / vessel heating where unusual shapes (cones, hoppers etc.) are encountered.

MI Cable may be used for most other general heat tracing applications if designed to provide the correct output. They may also be found in all underfloor (roads, ramps, sports grounds, horticultural, agricultural, space) heating duties where the mechanical strength of the cable is required.
