Mineral insulated cable advantages:
Since the entire material of this cable uses inorganic materials, it has the advantage that some other cables may not have.
1, fire-resistant
The two materials used in mineral insulated cables, copper and magnesium oxide, are inorganic. This cable will not burn, it will not support combustion, and it can continue to operate under conditions close to the flame. The copper sheath melts at 1083°C, while the magnesium oxide insulator cures at 2800°C.
2, high operating temperature
Mineral insulated cables withstand continuous operating temperatures up to 250°C. However, in emergency situations, the cable can be operated for a short period of time at a temperature close to the melting point of the copper sheath.
3, long life
Inorganic materials used in mineral insulated cables can guarantee stability, long life and fire resistance of cables.
4, explosion-proof
Highly compacted insulation material in mineral insulated cables prevents steam, gases and flames from passing between equipment parts connected to the cable.
5, small outside diameter
Mineral insulated cables are smaller in diameter than other cables with the same rated current.
6, waterproof
If the mineral insulated cable is completely immersed in water, the mineral insulated cable can continue to operate with its seamless metal sheath.
7, high mechanical strength
Mineral-insulated cables are rugged enough to withstand severe mechanical damage without compromising their electrical properties.
8, large current carrying capacity
For cables with the same cross-section, mineral insulated cables carry higher currents than other types of cables. At the same time, mineral insulated cables can also withstand considerable overload.
9, short circuit fault rating
At the same temperature, the short-circuit fault rating of mineral insulated cables is significantly higher than other types of cables.
10, grounding
For mineral insulated cables, separate grounding conductors are not required because the copper jacket used for this cable has acted as a grounding conductor and provides excellent low grounding resistance. For Grounded Skin Circuit (ESR) wiring, the outer copper sheath can be used as a ground and neutral conductor in a MEN (Multi-Ground Neutral) system.
11, high corrosion resistance
The copper jacket of mineral insulated cables is highly corrosion resistant and does not require additional protection for most devices. Where the copper sheathing of the cable is subject to chemical corrosion or serious industrial contamination, a plastic sheathed plastic insulated sheathed cable shall be used.
