The diameter of the mineral insulated cable is smaller than that of the other cables with the same rated current.
Waterproof, if the mineral insulated cable is completely immersed in water, with its seamless metal sheath, the mineral insulated cable can continue to operate.
The mechanical strength is high, the mineral insulated cable is strong and durable, it can withstand severe mechanical damage, and will not damage its electrical performance.
The current carrying capacity is large. For the same section cable, the mineral insulated cable has higher current than other types of cables. At the same time, mineral insulated cables can also withstand considerable overload.
Short circuit fault rating, at the same temperature, the short-circuit fault rating of mineral insulated cables is significantly higher than that of other types of cables.
Grounding, for mineral insulated cables, independent grounding wires are not necessary, because the copper sheath used for this cable has played the role of grounding wire and provides excellent low grounding resistance. As for the grounding skin loop (ESR) wiring, in the MEN (multi grounded neutral) system, the outer copper sheath can be used as grounding and neutral conductor.

The copper sheath of mineral insulated cable has high corrosion resistance. For most installations, it does not need additional protective measures. Where the copper sheath of cable is subject to chemical corrosion or serious industrial pollution, we should use plastic outer sheath to protect mineral insulated cables.
