Copper Conductor Mineral Insulated Cable for Petrochemical and Oil &Gas Platform is a Magnesium Oxide insulated copper conductor and sheath cable for the applications on the general lighting, emergency lighting line, computer room control line, large power line, high temperature environment power and control line, potential dangerous explosion area line etc for either coal fired or nuclear power plant.
Pasia also supply heating cable and heaters of mineral insulated cable for either coal fired or nuclear power plant.
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.
