Best Mineral Insulated Copper Cable

Product structure

Corrugated copper metal sheathed inorganic mineral insulated cable is mainly composed of the following parts:

1. Twisted copper conductor: As the current transmission part of the cable, it uses multiple strands of copper strands, which have the characteristics of low impedance, large current carrying capacity and good flexibility.

2. Inorganic insulation material: It uses high temperature resistant (up to 900℃) inorganic mineral insulation mica tape for wrapping, and the insulation layer is tight and uniform, moisture resistant and flexible.

3. Inorganic fiber filler: Inorganic paper rope is used to fill the outside of the insulation layer to enhance the mechanical properties and fire resistance of the cable.

4. Corrugated copper sheath: The copper strip is cut and then argon arc welded into a copper tube, and then continuously rolled and corrugated to form a corrugated copper sheath, which has good high temperature resistance and corrosion resistance.

5. Outer sheath (optional): Under specific requirements, a layer of polyolefin (low smoke zero halogen) sheath can be added to the corrugated copper sheath to improve the corrosion resistance and environmental performance of the cable.

Product characteristics

1. Excellent fire resistance: The finished cable is subjected to fire resistance test according to Chapter 6 of GB/T19216.21-2003, and the test conditions and results shall meet the requirements of 6.4.4. In addition, the finished cable with an outer diameter of ≤20mm is subjected to C, W, and Z tests on one sample according to the fire resistance performance provisions of Chapter 11 of BS6387:1994, and the line should remain intact; the finished cable with an outer diameter of ＞20mm is tested according to the provisions of BS8491:2008, and the line should remain intact.

2. Long continuous length: The continuous length of the finished cable can reach more than 2,000 meters, with no joints in the middle, fast heat dissipation, and can be bent. It can be made into multi-core cables with large cross-sections, which is convenient for construction and installation.

3. Large cross-section: The cross-section of a single-core cable can reach 630mm², and the cross-section of a multi-core cable can reach 240mm², which can meet various power supply needs.

4. Good flexibility: The cable can be wound on a cable drum, and its bending radius is small, which is convenient for transportation and installation.

5. Environmentally friendly and non-toxic: It is smokeless and non-toxic when burning, and the insulation layer is made of inorganic materials, which will not cause secondary pollution to the environment.

6. Corrosion resistance: The copper sheath has good corrosion resistance, does not require pipe protection, and extends the service life of the cable.

7. No electromagnetic interference: Under the shielding of the copper sheath, it will not interfere with the signals transmitted by wires and cables such as information and control.

8. Safe and reliable: It can supply power normally in the flame, start fire extinguishing equipment, reduce fire losses, and is also particularly reliable for personal safety.

Application fields

Corrugated copper metal sheathed inorganic mineral insulated cables are widely used in various places that require high fire resistance, explosion resistance, corrosion resistance and high temperature resistance, such as fire protection and power supply systems in high-rise civil buildings, office buildings, hotels, shopping malls, exhibition centers, museums, libraries, hospitals, gymnasiums, airports and other public places; flammable and explosive places such as petroleum, chemical, pharmaceutical, nuclear power, military and other enterprises; high temperature resistant places such as high temperature workshops such as steel, smelting, glass, etc.; and national defense projects such as aviation, aerospace, satellite launch, central control center, etc.
