Copper Sheathed MI Heating Cable with Two Cores Conductors Rated 600 V is a type of cable with maximum withstand temperature of the copper sheathed heating cable (MICU) provided by MICH can reach up to 250℃. Conductor resistance value ranges from 1.7-2000Ω/km. For the occasion of anti-corrosion or buried application, high density polyethylene (HDPE) outer sheath ( cable known as MIHC) is needed to be added. MIHC’s withstanding maximum temperature can be up to 90℃. Mineral insulated heating cable possesses excellent mechanical strength. The heating cable of series resistance provided by MICH can meet the requirements of different power levels. It is normally used for the industrial use with a higher output power required. Two cores' cable is more difficult to be produced but it is more covenient to be installed.
