The fireproof performance of the flexible fireproof cable is good, and the fire resistance can not only meet the fire resistance test procedure specified in Chapter 6 of the national standard GB/T19216.21-2003, but also pass the test under the conditions of 950 and 90 minutes (Class A 650 3h specified in British BS6387 can also be satisfied).

Various properties of flexible fireproof cables

Flexible Fireproof Cable Structure

1. Cable conductor: Stranded copper wire with good bending characteristics.
2. Insulation layer: Use high-temperature, non-combustible weapon insulation materials.
3. Copper sheath: Copper material, after special processing, has good bending characteristics, and is used as a ground wire.
4. Outer call layer: low-smoke and non-toxic plastic material is used, which has good anti-corrosion properties.

Advantages of flexible fireproof cables

1. The fireproof performance of the flexible fireproof cable is good, and the fire resistance can not only meet the fire resistance test procedure specified in Chapter 6 of the national standard GB/T19216.21-2003, but also pass the test under the conditions of 950 and 90 minutes (Class A specified in British BS6387) 650 3h can also be satisfied). Class B 7503H; Class C 950 3h requirements); at the same time, it can withstand water spray and mechanical shock during combustion.

2. Continuous length, single-core or multi-core cable, the length can meet the power supply length requirements, the limit length is up to 2000 meters;

3. Large cross-section, the single-core cable cross-section is 1000mm2 higher, and the multi-core cable cross-section is 240mm higher

4. Flexible, the cables can be installed on the cable tray. The bending radius is 20D, where D is the outer diameter of the cable.

5. It is non-toxic when burning and uses inorganic materials (non-combustible) for insulation. It will not produce any harmful gas or secondary pollution when burning. It can be said to be an environmentally friendly product.

6. The flexible fireproof cable not only has a large cross-sectional carrying capacity, but also has a large overload capacity. According to the wiring requirements, the surface temperature of the flexible fireproof cable is generally 70. If the wiring cannot be touched and does not touch flammable building materials, the temperature of the cable sheath can reach 105. The allowable working temperature of the fireproof cable is 250℃ when overloaded.

7. Anti-corrosion, organic insulated fire-resistant cables sometimes need to wear plastic pipes or steel pipes. Plastic is easy to age and rust, and fireproof cables do not need copper sleeves to pass through pipes, and copper sleeves are highly corrosive.

8. No electromagnetic interference, when the flexible fireproof cable and signal, control and other wires and cables are laid on the same axis, the fireproof cable is under the shield of the copper sheath, which does not interfere with the signal or the information transmitted by the control wire and cable.

9. Good security. In addition to powering the fire normally, the flexible fireproof cable also activates firefighting equipment to reduce fire losses. At the same time, personal safety is also particularly reliable. Its copper sleeve is a good conductor and the best grounding wire, which is connected to the entire length of the cable, which greatly improves the sensitivity and reliability of grounding protection.

10. Long service life, inorganic insulating material, high temperature resistance, not easy to aging. His life is several times higher than that of organic insulated cables, and under normal working conditions, its life may be the same as that of buildings.

11. The transportation and installation of flexible fireproof cables, the installation accessories are similar to ordinary cables, and are simple.

12. Due to the good economy, advanced manufacturing technology and easy installation of flexible fireproof cables, under the same conditions, the overall cost is obviously lower than that of mineral insulated cables.
