This product is suitable for metal-sheathed inorganic mineral-insulated fire-resistant cables with a rated voltage of 0.6/1kV and below. It uses multi-strand stranded copper wire as the conductor, inorganic mineral insulation tape as insulation, and a welded copper strip tube as the sheath. If necessary, a plastic outer sheath can be extruded over the copper sheath. For special applications requiring smokeless and halogen-free conditions, a low-smoke, halogen-free sheath can be added over the copper sheath.

Product Advantages

1. Excellent fire resistance: The fire resistance rating not only meets the international standard GB12666.6 Class A 950℃ for 90 minutes, but also meets the requirements of British BS6387-1994 Class A 650℃ for 3 hours; Class B 750℃ for 3 hours; and Class C 950℃ for 3 hours. It can also withstand water spray and mechanical impact during combustion.

2. Long continuous length: Whether single-core or multi-core, the length can meet power supply needs, with each continuous length exceeding 1000m.

3. Large cross-section: Single-core cable cross-section can reach 630 mm², and multi-core cable cross-section can reach 70 mm².

4. Flexible: The cable can be coiled on a cable reel with a bending radius of 6-10D (D is the cable outer diameter).

5. It burns without smoke or toxicity. The insulation uses inorganic materials (non-combustible), producing no harmful gases and causing no secondary pollution during combustion, making it a truly environmentally friendly product.

6. High overload capacity: The cable not only has a large current-carrying capacity but also a significant overload capacity. According to wiring specifications, the cable surface temperature is typically ≤70℃. If the wiring is not to be touched and does not come into contact with combustible building materials, the cable sheath temperature can be increased to 105℃. Under overload conditions, the long-term operating temperature of the fire-resistant cable can reach 250℃.

7. Corrosion resistance: Organically insulated fire-resistant cables sometimes require plastic or iron pipes. Plastic pipes are prone to aging and becoming brittle, and iron pipes are prone to corrosion. Fire-resistant cables have a copper sheath that does not require puncture, and the copper sheath has excellent corrosion resistance.

8. No electromagnetic interference: When fire-resistant cables are laid in the same shaft as information and control lines, the copper sheath shields them from interference with the information transmitted by the signal and control cables.

9. High safety: Fire-resistant cables can supply power normally in flames, activating fire extinguishing equipment, reducing fire losses, and are particularly reliable for personal safety. Their copper sheath is an excellent conductor, the best grounding PE wire, and continues to the entire length of the cable, greatly improving the sensitivity and reliability of grounding protection.

10. Long service life: Inorganic insulation materials are resistant to high temperatures and do not easily age. Their lifespan is many times longer than that of organic insulated cables, reaching over 100 years under normal operating conditions.

11. Good economy: Due to advanced manufacturing processes and simple installation, flexible fire-resistant cables have a significantly lower overall cost than mineral-insulated cables under the same conditions.
