Stranded Copper Conductor Mineral Isulated Copper Sheathed High Tension LSZH Sheathed Cable
Mineral insulated cable is a kind of cable in which copper conductor core is wrapped with copper sheath and magnesium oxide powder is used as inorganic insulating material to isolate conductor and sheath. The outermost layer can choose appropriate protective sheath as needed. Commonly known as MICC or MI cable.
Product Description
1. Fire resistance
Copper and mineral insulation of the two materials used in mineral insulation cables are inorganic materials. The cable does not burn or help fuel, and can continue to operate under conditions near the flame. The copper sheath was melted at 1083 °C.
2. High operating temperature
Mineral insulated cables can withstand continuous operating temperatures up to 250°C and, in an emergency, the cables can continue for a short time near the melting point of the copper sheath.
3. Durable
Inorganic materials used in mineral insulated cables can guarantee cable stability, durability and fire resistance.
4. Explosion-proof
Highly compacted insulation in mineral insulated cables that prevents steam, gas and flames from passing between parts of the equipment connected to the cable.
5. Small outer diameter
Mineral insulated cables have a smaller diameter than other cables with the same rated current.
6. Waterproof
If mineral insulation is completely submerged in water to assist the metal sheath, mineral insulation may be continued.
7. High mechanical strength
Mineral insulated cables are strong and durable to withstand severe mechanical damage without compromising their electrical properties.
8. Large load flow
For the same section, mineral insulated cables transmit higher current than other types of cables. At the same time, mineral insulated cables can also withstand considerable overload.
9. Short-circuit fault fixed value is high
At the same temperature, the short circuit fault fixed value of mineral insulated cables is significantly higher than the other cables.
10. Copper sheath can be used as a grounding wire
For mineral insulated cables, independent grounding wires are not required because the copper sheath used in this cable has acted as grounding wires to provide good low grounding resistance. In terms of ground leather loop (ESR) wiring, the outer copper sheath can be used as a ground and neutral conductor in the MEN multi-ground neutral) system.
11. High corrosion resistance
The copper sheath of mineral insulated cables has high corrosion resistance and for most devices does not require additional protection. Mineral insulated cables shall be protected with plastic sheath where copper sheath are susceptible to chemical corrosion or severe industrial pollution.
Application: Mineral insulated cables have been widely used in high-rise buildings, petrochemical industries, airports, tunnels, ships, offshore oil platforms, aerospace, iron and steel metallurgy, shopping centers, parking lots and other places.
