Why are flexible fireproof cables so popular?

Flexible fireproof cable, also known as "inorganic mineral insulated cable", is developing rapidly in China because it is softer and easier to install than mineral insulated cable.

2、 Product benefits

1. Excellent fire resistance: the fire resistance rating not only meets the national standard GB12666.6 Class A 950 ℃, 90min, but also meets the British BS6387-1994 Class A 650 ℃ 3h Class B 750 ℃ 3h Class C 950 ℃ 3h test requirements; At the same time, it can withstand water jet and mechanical impact during combustion;

2. Long continuous length: whether single core or multi-core cable, its length can meet the needs of power supply length, and each continuous length can reach 1000m;;

3. Large cross-section: the cross-section of single core cable can reach 1000mm, and that of multi-core cable can reach 240mm;

4. Good flexibility: the cable can be coiled on the cable reel with a bending radius ≤ 20D (D is the outer diameter of the cable);

5. Smoke free and non-toxic during combustion: the insulation is made of inorganic materials (incombustible materials), which will not produce any harmful gas and secondary pollution during combustion, so it can be called an environment-friendly green product;  

6. Large overload capacity: the cable not only has large current carrying capacity, but also has large overload capacity. According to the wiring requirements, the surface temperature of the cable is generally ≤ 70 ℃. If the wiring is untouchable and does not contact with combustible building materials, the temperature of the cable sheath can be increased to 105 ℃, and the long-term working temperature of the flexible fireproof cable can reach 250 ℃ when overloaded;

7. Corrosion resistance: Organic insulated fire-resistant cables sometimes need to go through plastic pipes or iron pipes. The plastic pipes are easy to be aged and brittle, and the iron pipes are easy to rust. The fire-resistant cables with copper sheaths do not need to go through the pipes. The copper sheaths have good corrosion resistance;

8. Good shielding performance: when the fireproof cable is laid in the same shaft with the information and control wires, it will not interfere with the information transmitted by the signal and control wires and cables under the shielding of the copper sheath;

9. Safe and reliable: the fireproof cable can supply power normally in the flame, start the fire-fighting equipment, reduce fire losses, and is particularly reliable for personal safety. Its copper sheath is a good conductor, the best grounding PE wire, and it is continuous to the full length of the cable, greatly improving the sensitivity and reliability of grounding protection;

10. Long service life: inorganic insulating materials have high temperature resistance and are not easy to age. Their service life is many times higher than that of organic insulated cables. Under normal working conditions, their service life can reach more than 100 years;

11. Simple installation: the transportation and installation of flexible fireproof cables, including installation accessories, are similar to ordinary cables, which is relatively simple;

12. Low installation cost: due to advanced manufacturing technology and simple installation, the comprehensive cost of flexible fireproof cable is significantly lower than that of mineral insulated cable under the same conditions.
