YTTW BTTRZ Mineral Insulated Cable Fireproof Cable Flexible Fireproof Cable

Purpose
Flexible fireproof cable is also called copper sheathed corrugated inorganic insulated cable. This cable is a new type of fireproof cable that has been improved on the disadvantages of mineral insulated cables. It can overcome the disadvantages of limited production length of mineral insulated cables, avoid the problem of intermediate joints during installation and laying, and has an insulating layer that is not susceptible to moisture. With the advantages of convenient installation and laying, with the continuous promotion of this product, its excellent performance is increasingly recognized by customers, and it is now widely used in basic industry and civil construction
Features
Series Metal Guard The conductor of the inorganic mineral insulated power cable is made of multi-stranded copper wires. The insulation is mechanically wrapped with high-temperature resistant synthetic mica tape. The outside of the insulation layer is densely filled with alkali-free glass fiber. The sheath is wrapped longitudinally with copper tape and then welded into a copper tube. Then it is corrugated by continuous rolling. When there are specific requirements that the metal sheath cannot be exposed, a layer of polyolefin low-smoke halogen-free sheath can be added to the outside.
This product is the first of its kind in China and there is no prototype in the world. Compared with the series, the product maintains a high degree of fire resistance while being able to achieve continuous large lengths, ㎜? It can also be made into multi-core group cables, which overcomes the disadvantage of too many joints and too difficult construction. However, the welds of corrugated copper pipes are prone to cracking of single mica insulation, which has also become a congenital structural defect, and the requirements for installation process capabilities are still very high.
Main functions
Excellent fire resistance, the fire resistance level not only meets the national standard ℃, but also meets the requirements of grade ℃ and grade ℃ specified in the UK. At the same time, it can also withstand water spray and mechanical impact during combustion
Long continuous length, whether it is a single-core or multi-core cable, its length can meet the power supply length needs, each continuous length can reach above
Large cross-section, single-core cable cross-section can reach up to
It is flexible, the cable can be coiled on the disk, and its bending radius
It is smoke-free and non-toxic when burned. The insulation is made of inorganic materials. It will not produce any harmful gases when burned, let alone secondary pollution. It is A true environmentally friendly green product with large overload capacity. The cable not only has a large carrying capacity, but also has a large overload capacity. According to the wiring instructions, the surface temperature of the cable is usually ℃. If the wiring cannot be touched and is not in contact with flammable building materials, the temperature of the cable sheath can be increased to ℃. The long-term working temperature of fireproof cables can reach ℃ when overloaded
Corrosion resistance, good shielding performance, and copper sheath have good corrosion resistance. In special or corrosive environments to copper, a layer of low smoke should be added to the copper sheath. Halogen-free or plastic outer sheath. Under the shielding of the copper sheath, there is no electromagnetic interference and will not interfere with the information transmitted by the signal control wires and cables. It has good safety. The fireproof cable can provide normal power supply in the flame for more than 1 hour. Normal power supply starts the fire extinguishing device, reducing Fire damage. The copper sheath is an excellent conductor and the best grounding wire, which greatly improves the sensitivity and reliability of grounding protection. It has a long service life, is resistant to high temperatures and is not prone to aging. Under normal working conditions, its service life is more than a year.
The transportation, installation and installation accessories of flexible fire-proof cables are relatively simple, similar to ordinary cables
Economically good, flexible fire-proof cables have advanced production technology and simple installation. Under the same conditions, their overall cost is higher than that of mineral insulated cables. The cost should be low.
