Product description

0.6/1 kV flexible mineral fireproof cable is mainly used in trunk lines, firefighting lines, escape and rescue systems, such as emergency lighting, fire monitoring, alarm system, elevator system, smoke exhaust system, and control circuit. The product fully meets national and industry standards such as GB/T13033 Mineral Insulated Cables and Their Terminations with a Rated Voltage not Exceeding 750 V, JG/T313 Metal Sheath Inorganic Mineral Insulated Cables and Their Terminations with a Rated Voltage not Exceeding 0.6/1 kV, GB/T 19666 Flame Retardant and Fire Resistant Wires and Cables and IEC 61034-2, and enterprise standard requirements of Q/QL 01-2023 Flexible Mineral Insulated Fireproof Cables with Rated Voltage of 0.6/1 kV.

1, superior fire performance: burning performance grade to GB 31247 "cable and optical cable burning performance classification" A non-combustible cable, total calorific value PCS ≤ 2.0MJ/kga (unit mass of the material completely burned, all the water vapor condensed into water in the combustion products of all the heat released).

2, good flexibility: single-core cable its minimum bending radius ≤ 20D, multi-core cable minimum bending radius ≤ 15D (D cable outside diameter).

3, green: copper conductors, four layers of mica tape overlap wrapping and cross-linked polyethylene double insulation, mineral (or rock wool rope) filling, mineral (or glass fiber) wrapping tape, the use of vitrified polyolefin inorganic mineral protective layer material (non-combustible body), when burning, the outer sheath of halogen-free low smoke flame retardant cross-linked polyolefin and metal sheath. Will not produce any harmful gases, not to mention the secondary pollution.

4、Large overload capacity: the cable not only has a large load capacity, but also has a large overload capacity. According to the wiring requirements, the normal operation of the cable sheath surface ≤ 70 ℃, if the wiring is not touchable and not in contact with combustible materials, the cable sheath surface temperature can be increased to 105 ℃, overload conductor surface temperature can reach 250 ℃ in the long term.

5, corrosion resistance: organic insulation fire-resistant cable through the tube, PVC pipe is easy to aging, iron pipe prone to rust, fire-resistant cable has a metal sheath does not need to wear a tube, copper sheath corrosion resistance is good.

6, good shielding performance: fire-resistant cables and signal network lines, control cables, etc., when laid in the same shaft, under the shielding of the copper sheath, will not interfere with the information transmitted by the signal network lines, control cables.

7, safe and reliable: fire-resistant cable can be powered normally in the flame to ensure that it can start fire-fighting equipment to reduce fire losses, particularly reliable for personal safety, its copper sheath has excellent electrical conductivity, but also the best grounding PE wire, greatly improving the sensitivity and reliability of grounding protection.

8, long service life: inorganic insulation material is resistant to high temperature, not easy to aging, under normal working conditions, its service life is more than 3 times higher than organic insulation cable.

9, application range: high-rise buildings, underground buildings, hotels and restaurants, hospitals, schools, business centers, government centers, department stores, large supermarkets, logistics warehouses, banks, securities and insurance and other financial institutions, post and telecommunications centers, power control rooms, substation rooms, museums, memorials and other historic buildings.
