Mineral insulated cable (Mineral insulated cable), a cable that wraps the copper conductor core wire with a copper sheath, and uses magnesium oxide powder as an inorganic insulating material to isolate the conductor and the sheath. The outermost layer can be selected with an appropriate protective sheath. Commonly known as MICC or MI cable. There is a similar cable that uses metal instead of copper sheath to wrap the core wire and insulation material, called mineral insulated metal sheathed cable.

1. Explosion-proof and corrosion-resistant
Explosion-proof characteristics: Since mineral insulated cables use metal sheaths as protective layers, flammable gases, oil vapors, and flames cannot reach the electrical equipment connected to the cables, so the cables have explosion-proof characteristics.
Corrosion resistance: Since copper has good corrosion resistance, it does not need any additional protection under normal use environment. Add a layer of PVC outer sheath, so the cable has good corrosion resistance.
2. Resistance to mechanical damage, long life, halogen-free and non-toxic
Resistance to mechanical damage: Since the metal sheath of the cable has certain strength and toughness, the relative position between the core wires and between the core wires and the sheath remains unchanged when the cable is subjected to deformation such as bending, flattening, and torsion. There will be no short circuit and no impact on electrical performance.
Long service life: Since the materials used in the cable are all inorganic materials, they will not age. Its service life can be calculated according to the rate of oxidation and corrosion of the copper sheath. According to the data, it takes 257 years for the sheath to oxidize 0.25mm at an ambient temperature of 250°C, while the thickness of the sheath of mineral insulated cables is generally between 0.34-1.05, and the operating temperature is lower than 250°C, so the cable has Features of long life.
Halogen-free and non-toxic: Since the cables are all composed of inorganic substances (metal copper and mineral insulating layer), even if they are burned at a high temperature of 1000°C, they will not produce smoke, halogen and toxic gases. It is truly halogen-free and non-toxic cable.
3. Overload resistance, copper sheath can be used as grounding wire
Overload resistance: Since the melting point of copper is 1083°C and the mineral insulating layer is also above 1000°C, compared with ordinary plastic cables, the carrying capacity of mineral insulated cables can be increased by a section level, and at the same time, it can withstand considerable overload. The capacity can reach more than 10 times the normal carrying capacity.
The copper sheath can be used as a grounding wire: for mineral insulated cables, due to the continuity and extremely low grounding resistance of the copper sheath, it can be used as a grounding wire and does not require an independent grounding wire.
