Steel and Metallurgy Industry Use Mineral Insulated Cable of Copper Sheath and Conductor is the MI cable to be used in Steel and metallurgy in on high temperature environment power and control line, emergency power supply, large power line, power supply line that cannot be cut off, power transmission line in generator room etc.
Pasia also supply heating cable and heaters of mineral insulated cable for Steel and Metallurgy Industry.
Since the cables are all composed of inorganic materials (magnesium oxide) and copper, they themselves do not cause fire and are unlikely to burn or assist combustion. Since the melting point of copper is 1083℃, and the melting point of magnesium oxide is 2800℃, this kind of cable can continue to maintain power supply in the case of fire near the melting point of copper, which is a kind of fire prevention cable. At present, it is the only safe electricity transmission cable that can maintain power supply capacity for three hours in a 1000℃ fire and can withstand the impact of fire water spraying and heavy weight falling.
Composition of Mineral insulated cable
Mineral insulated cable is a kind of cable which uses annealed copper as conductor, dense magnesium oxide as insulation and annealed copper pipe as sheath. If necessary, it can be squeezed with a layer of plastic outer sheath around the annealed copper sheath. For specially required occasions, a layer of low-smoke halogen free sheath can be applied.
Advantages of Mineral Insulated Cables
Since all the materials of this cable are inorganic, it has some advantages that other cables cannot have, such as, fire prevention, high current carrying capacity, resistance to mechanical damage, non-toxic, non-halogen, explosion-proof, waterproof, corrosion resistance, long life, safety, overduty resistance, high temperature resistance, low cost, small bending radius, anti-ant, anti-rat bite, copper sheath used as a protective grounding wire and so on.

Mineral insulated cable long - term operating temperature is 70℃, in unmanned occasions, the long-term working temperature of material insulated cable is 105℃. In special high temperature occasions, the long-term working temperature can be up to 250℃. At 950-1000℃, it can continue power supply for more than 3h with the short or very short period, working temperature can reach 1083℃.
The minimum allowable bending radius of mineral insulated cables conforms to a range of certain times of the cable diameter.
