Yanggu Haohui FlexibleFireproof cableThe characteristics of the, small make up to introduce to you.
1. The fire resistance performance is excellent. The fire resistance rating not only meets the requirements of international GB12666.6A 950 ℃ for 90min, but also meets the requirements of British BS6387-1994 for Grade A 650 ℃ 3hB 750 ℃ 3hC 950 ℃ 3h. At the same time, it can withstand water spray and mechanical impact during combustion.
2. Continuous length is long. Whether it is single-core or multi-core cable, its length can meet the needs of power supply length, and the limit length can reach 2000m.
3. The cross section of large single-core cable can reach 1000mm2 and the cross section of multi-core cable can reach 240 mm2.
4. With flexibility, the cable can be rewound on the cable reel with a bending radius ≥ 20D, and D is the outer diameter of the cable.
5, when burning smoke-free non-toxic, insulation using inorganic materials "non-burning body", combustion will not produce any harmful gases, but will not occur secondary pollution, can be called environmental protection green products.
If the cross-sectional capacity is too large, the cable not only has a large cross-sectional flow but also has a large overload capacity. According to the wiring requirements, the cable surface temperature is usually less than or equal to 70 ℃. If the wiring is not touchable and not in contact with combustible building materials, the cable sheath temperature can reach 105 ℃. The allowable working temperature of the fireproof cable can reach 250 ℃ when overloaded.
7, corrosion resistance, organic insulation fire-resistant cable sometimes need to wear plastic pipe or iron pipe, plastic is easy to aging brittle, iron pipe is easy to rust; fireproof cable is copper sheath does not need to wear pipe, copper sheath corrosion resistance is good.
8, no electromagnetic interference, fireproof cable and signal, control and other wires and cables are laid in the same shaft. Fireproof cables are shielded under a copper sheath. It will not interfere with the information transmitted by the signal? Control wire and cable.
9, good safety, fireproof cable in addition to the normal power supply in the flame, start fire extinguishing equipment, reduce fire loss. At the same time, it is also particularly reliable for personal safety. Its copper sheath is a good conductor, is a grounding 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 materials, high temperature resistance, and not easy to aging, his life than the organic insulation cable increased many times?, in normal working conditions, its life can be equivalent to the building.
