The cable range of stainless steel 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, it has combined a stainless steal sheath with heating conductors to enable an operating temperature of 600℃ with resistance values from 2.1Ω/km down to 36100Ω/km.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.
