Mineral Insulated Cable (MCN)

The MCN range of cupronickel sheathed Mineral Insulated (MI) heating cable has been developed to meet the specific need for a cable having a high temperature capability and electrical resistance values needed for long circuit lengths. To meet the requirement, Heat Trace has combined a cupronickel sheath with heating conductors to enable an operating temperature of 400ºC with resistance values from 4Ω/km up to 28000Ω/km per conductor. MI cables have excellent mechanical strength and are resistant to corrosion. They are series resistance heaters which must be designed to provide the required heat output.
