As the mineral cables are all made of inorganic composition, which itself does not cause a fire, can not burn or combustion, not to produce toxic gases, even in the flame burning, the cable can still work.
After the fire is cleared, the cable does not need to be replaced, which is a true sense of the fire cable.
Since mineral-insulated cables can be used at temperatures up to 250 ° C, the IEC 60702 specifies a continuous operating temperature of 105 ° C for mineral-insulated cables, taking into account the end-sealing material and safety requirements, even if the cut-off is far greater than that of other cables Magnesium oxide powder has a better coefficient of conductivity than plastic, so the same operating temperature, the greater the amount of cut-off for 16mm or more lines.
As the cable with low smoke and halogen-free high flame retardant materials for the sheath with high corrosion resistance (plastic outer sheath is only in the occasion of individual chemical corrosion needs), conductor, insulation, and sheath compacted compact between the three. So it not only has to prevent water, moisture, and oil.
