Products Description
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.
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.

Products advantages
Since all the materials of this cable are inorganic materials, it
has some advantages that other cables cannot have.
1. Refractory
The two materials copper and mineral insulation used in mineral
insulated cables are inorganic. This kind of cable will not burn or
support combustion, and can continue to operate under conditions
close to flames. The copper sheath melts at 1083°C.
2. High operating temperature
Mineral insulated cables can withstand continuous operating
temperatures up to 250°C. And, in an emergency, the cable can
continue to operate for a short time at a temperature close to the
melting point of the copper sheath.
3. Long life
Inorganic materials used in mineral insulated cables to ensure the
stability, long life and fire resistance of the cables.
4. Explosion-proof
The highly compacted insulation in mineral insulated cables
prevents the passage of vapors, gases and flames between parts of
equipment to which the cable is connected.
5. Small outer diameter
Mineral insulated cables have a smaller diameter than other cables
with the same current rating.
6. Waterproof
With its seamless metal sheath, MI cables continue to operate if
fully submerged in water.
7. High mechanical strength
Mineral insulated cables are robust and can withstand severe
mechanical damage without compromising their electrical properties.
