Product Description
YTTW Fireproof Cable, a high-performance solution designed to withstand extreme temperatures and ensure safety in critical applications. This mineral insulated fireproof cable is specifically engineered for low voltage use with a rated voltage of 0.6/1 KV, making it ideal for construction, industrial, and other demanding environments.
Constructed with pure copper conductors, the YTTW cable ensures excellent conductivity and durability. Its mineral insulation provides superior heat resistance and fireproof capabilities, allowing it to maintain functionality even under the most challenging conditions. The cable is also available in various lengths to meet specific project requirements.
Product standard
JG/T 313-2014, GB/T 34926-2017, BS 6387.
Corrugated copper sheathed mineral insulated cable YTTW characteristics
1. Excellent fireproof performance. The fire resistance grade not only meets the national standard GB12666.6A 950°C, 90min, but also meets the A grade 650°C3h specified in British BS6387-1994; the B grade 750°C3h; the C grade 950°C3h requirement; 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, each continuous length can reach more than 1000m;
3, large cross section, single core cable section up to 630mm2, multi-core cable up to 70mm2;
4, with flexibility, the cable can be placed on the disk, its bending radius is 6-10D;
5. Smokeless and non-toxic when burning, inorganic materials are used for insulation, no harmful gas will be generated when burning, and no pollution will occur twice. It is a truly environmentally friendly green product;
6, the overload capacity is large, the cable not only has a large carrying capacity, but also has a large overload capacity. According to the wiring instructions, the cable surface temperature is usually ≤70 °C. If the wiring is not touchable and does not come into contact with combustible building materials, the cable sheath temperature can be increased to 105 °C. Long-term working temperature of fireproof cable up to 250 °C during overload
7. Corrosion resistance, good shielding performance, good corrosion resistance of copper sheath. In the environment of special or corroded copper, a layer of low-smoke halogen-free or plastic outer sheath should be added to the copper sheath. Under the shielding of the copper sheath, there is no electromagnetic interference, and it will not interfere with the information transmitted by the signal and the control wire and cable.
8. Good safety, fireproof cable can supply power normally in flame (normal power supply for more than 3 hours at 950 °C), start fire extinguishing device, reduce fire loss. Copper sheath is a good conductor and is the best grounding wire to greatly improve the sensitivity and reliability of grounding protection.
9, long service life, high temperature resistance is not easy to aging, under normal working conditions, its service life is more than 100 years.
10. The transportation, installation and installation of flexible fireproof cables are relatively simple, similar to ordinary cables.
11. The economy is good. Due to the advanced production process and simple installation, the flexible fireproof cable has lower comprehensive cost than the mineral insulated cable under the same conditions.
