What is Mineral Insulated (MI) Cable?
Mineral Insulated cables feature conductors enclosed by a metal jacket and insulated with hard-packed Magnesium Oxide (MgO). This construction provides exceptional electrical isolation, physical protection, and high-temperature capability in harsh environments.
- Construction: Copper or thermocouple wires inside copper, stainless steel, or Inconel sheath
- Insulation: Magnesium oxide provides chemical and physical stability at high temperatures
- Configurations: Available with 1, 2, or 3 pairs of conductors, plus custom configurations
- Applications: Heat treating metals, solid waste incinerators, sintering powdered metals, ceramic firing, furnaces, and energy plants
