The raw material of flexible fireproof cable is copper conductor, which has high temperature resistance and belongs to industrial classification. Flexible fireproof cable, also known as "inorganic mineral insulation cable", because it has the characteristics of softer than mineral insulation cable, easy to install and lay, is currently developing rapidly in China.
Advantages of flexible fireproof cable products:
1. Excellent fire resistance: the fire resistance grade not only meets the national standard GB12666.6 A class 950 °C, 90min, but also meets the British BS6387-1994 specified in the A class 650 °C 3h; , B grade 750 °C 3h; C class 950 °C 3h test requirements, at the same time, in the combustion can also withstand water spray and mechanical impact.
2. Continuous length length: whether it is a single core or a multi-core cable, its length can meet the needs of power supply length, and each continuous length can reach 1000m.
3. Large cross-section: single-core cable cross-section up to 1000mm, multi-core cable cross-section up to 240mm.
4. Good flexibility: the cable can be coiled on the cable tray, and its bending radius ≤ 20D, (D is the outer diameter of the cable).
5. Smokeless and non-toxic during combustion: The insulation adopts inorganic materials (non-combustion body), and no harmful gases will be produced when burning, and secondary pollution will not occur, which can be called an environmentally friendly green product.
6. Large overload capacity: The cable not only has a large ampacity, but also has a large overload capacity. According to the wiring to show, usually the cable surface temperature ≤ 70 °C, if the wiring is not touchable, nor in contact with combustible building materials, the cable sheath temperature can be increased to 105 °C, overload flexible fireproof cable long-term working temperature up to 250 °C.
7. Corrosion resistance: organic insulation refractory cable sometimes needs to wear plastic pipe or iron pipe, plastic pipe is easy to age and brittle, iron pipe is easy to rust, fireproof cable has copper sheath does not need to wear the pipe, copper sheath corrosion resistance is good.
8. Good shielding performance: When the fireproof cable is laid in the same shaft as the information and control wire, under the shielding of the copper sheath, it will not interfere with the information transmitted by the signal and the control wire and cable.
9. Safe and reliable: fireproof cable can normally supply power in the flame, start the fire extinguishing equipment, reduce fire loss, and is particularly reliable for personal safety, its copper sheath is an excellent conductor, is the best grounded PE wire, and is continuous to the full length of the cable, which greatly improves the sensitivity and reliability of grounding protection.
10. Long service life: inorganic insulation material has high temperature resistance and is not easy to age, its life is many times higher than that of organic insulated cable, and its life can reach more than 100 years in normal working conditions.
11. Simple installation: The transportation and installation of flexible fireproof cables includes installation accessories similar to ordinary cables, which is simpler.
12. Low installation cost: Due to the advanced production process and simple installation of flexible fireproof cables, their comprehensive costs are significantly lower than the cost of mineral insulated cables under the same conditions.
