Product Introduction of Ceramic Flexible Mineral Insulated Fireproof Cable BTTWY/BTRWY

Composition of Flexible Mineral Insulated Fireproof Cable (BTTWY) (BTRWY)
Flexible mineral insulated fire-resistant cable is composed of copper stranded wire, mineral compound ceramic fire-resistant composite tape insulation, and sheath. Although this type of cable still contains a small amount of organic material, it has non combustible, low smoke, non-toxic, and fire-resistant characteristics.
Flexible mineral insulated fire-resistant cable BTTWY/BTRWY plays an important role in protecting life, materials, and information security. It is applied in trunk lines, fire protection lines, escape and rescue systems, emergency lighting, fire detection, alarm systems, elevator systems, smoke exhaust systems, and control lines. Mainly used in high-rise buildings, underground buildings, hotels and restaurants, hospitals, schools, business centers, government centers, department stores, large supermarkets, logistics warehouses, banks, securities, insurance and other financial institutions, postal and telecommunications centers, power control rooms, substations, museums, memorial halls and other historic buildings.
The Top 15 Characteristics of BTTWY/BTRWY Cables
1. Flame retardant properties:
The main materials of BTTWY/BTRWY cables (inorganic substances or compounds, ultra-high flame retardant sheathing materials) determine the non flammability, non spread of fire, and non spread of fire of the cable body.
2. Fire protection characteristics:
BTTWY/BTRWY cables strictly adhere to the currently most stringent BS6387 fire protection standard, ensuring at least 3 hours of valuable time for necessary personnel and property rescue in the event of a fire.
(The fire resistance performance of BTTWY/BTRWY fire-resistant cables can meet the following standard requirements)
Meets the fire resistance requirements of Class A (950 ℃, rated voltage applied for 90 minutes, insulation not damaged) in GB12666
Complies with the fire resistance requirements of Class C (950 ℃, rated voltage applied for 180 minutes, 3A fuse not fusing) in BS 6387
Complies with the fire resistance requirements for Class W in BS 6387 (650 ℃, water spray for 15 minutes, rated voltage applied, 3A fuse not fusing) with spray
Meets the fire resistance requirements for Class Z (950 ℃, subjected to mechanical impact for 15 minutes, rated voltage applied, 3A fuse not fusing) with impact in BS 6387
3. Soft characteristics:
The BTTWY/BTRWY cable structure does not have the metal sleeve of traditional fire-resistant cables, and uses an insulation reinforcement layer to protect mica. At the same time, a highly flexible thermoplastic sheath material is used, which determines that the cable itself is also softer than other fire-resistant cables.
4. Whole consistency:
BTTWY/BTRWY cables can be produced in fixed lengths, can be coiled, and do not require intermediate joints due to their reasonable material and structure.
5. Easy installation:
Due to the high flexibility and fixed length production of BTTWY/BTRWY cables, this cable is very convenient for construction, without the need for intermediate joints or dedicated terminals. Generally, electrical installation personnel can follow the conventional cable laying method.
6. Moisture proof characteristics:
The BTTWY/BTRWY cable adopts a new structure of synthetic mica tape and a reinforced insulation layer with moisture-proof function, effectively avoiding the problem of mica being prone to moisture.
7. Long term stability
The BTTWY/BTRWY cable itself has good moisture resistance and will not shorten its service life due to moisture. Moreover, mineral inorganic compounds can effectively act as oxygen barriers, prevent conductor oxidation, and have good heat dissipation function without being exposed to high temperatures. The main material of the cable itself is inorganic, so the service life of the cable can reach 60 years, which is equivalent to the service life of general buildings.
8. Environmental characteristics:
The materials used in BTTWY/BTRWY cables are all inorganic and low smoke halogen-free materials, so they will not produce toxic gases under fire conditions, completely overcoming the "disaster" and "secondary warning" caused by the smoke and toxicity generated by ordinary cables in flame combustion.
9. Temperature resistance characteristics:
BTTWY/BTRWY cables not only have a mica tape layer in insulation, but also radiation cross-linked polymer materials. The cables can operate reliably for a long time at 125 ℃.
10. Corrosion resistance:
The BTTWY/BTRWY cable sheath adopts corrosion-resistant thermoplastic low-voltage halogen-free sheath material, and the main internal materials are also inorganic substances, so the cable has strong corrosion resistance function, and no additional measures can be added during laying.
11. High current carrying capacity:
Compared to conventional fire-resistant cables with the same cross-section, BTTWY/BTRWY cables can not only transmit higher currents but also withstand larger overloads.
12. Full range:
BTTWY/BTRWY cables can be customized into single core or multi-core structures, or even pre branch structures, according to the actual needs of cable users. They can almost cover various specifications of building wires and cables such as power cables and control cables.
13. Low construction cost:
The installation of BTTWY/BTRWY cables is simple and does not require special processes, resulting in a significant reduction in construction time and cost.
14. High cost-effectiveness of the product:
The structure of BTTWY/BTRWY cable products is a rigid mineral insulated cable with non-metallic (copper tube, aluminum tube, stainless steel tube) sleeves, which fundamentally reduces the cost and does not require specialized intermediate joints and terminals. At the same time, it has the same fire resistance as the metal sleeve, which significantly improves the cost-effectiveness.
15. Public welfare:
The BTTWY/BTRWY cable, due to its improved structure, cleverly uses minerals and mineral compounds, which not only saves valuable copper resources but also saves a lot of energy consumption. Its public welfare value is also very significant.
