Mineral insulated (MI) heating cable
Mineral insulated heating cables consisting of one or two conductors in a highly compacted magnesium oxide insulation, which is surrounded by a seamless metal sheath. The heating cables are provided with cold ends, which are soldered or welded by connecting sleeves. The inner conductors consist of different resistance materials. Depending to the supply voltage, heater length and resistivity, a corresponding heat power results. The heating cables can be manufactured with various outer coats and thus satisfy the desired temperature and corrosion resistance. Operating temperatures up to +1000 °C are possible.
