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.
Application field
Mineral insulated cables have been widely used in high-rise buildings, petrochemicals, airports, tunnels, ships, offshore oil platforms, aerospace,
Iron and steel metallurgy, shopping centers, parking lots and other occasions.

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.
1.When can I get the price? We usually quote within 6 hours after we get your inquiry. If you are very urgent to get the price,please call us or tell us in your e-mail so that we will regard your inquiry priority.
2.How can I get a sample to check your quality? After price confirmation, you can require for samples to check our quality. Sample is free, but the freight charge should be paid.
3.How long can I expect to get the sample? After you pay the freight charge and send us confirmed files, the samples will be ready for delivery in 3-7 days. The samples will be sent to you via express and arrive in 3~5 days. You can use your own express account or prepay us if you do not have an account.
4.What about the lead time for mass production? Honestly, it depends on the order quantity and the season you place the order.The best record we keep is delivering 10 kilometers cable within a week.
