Are flexible fire cables advantageous in any way?

I. Flexible fire protection cable advantages in which aspects? Flexibility:As the conductor of the cable adopts mature stranding technology, it has the characteristics of anti-mechanical impact and flexible bending at the same time, which can avoid the trouble of installation of wiring terminals and the problem of delivery length that are often encountered when designing and installing rigid mineral insulated cables. Low smoke: according to IEC1034 smoke dispersion test, GB/T17651.2-1998 cables and fiber optic cables in specific conditions of combustion smoke density measurement, the test transmittance of more than eighty percent (the standard is sixty percent). Halogen-free: As mineral cable insulation and sheath are made of inorganic materials, without the usual PVC materials, so even under fire conditions, there is no acidic gas generation. According to GB/T17650.2-1998 taken from the cable material combustion gas release test test, PH value can reach more than 5.0 (standard requirements for ≥ 4.3), conductivity up to 1.0 or so (standard requirements for ≤ 10.0) Temperature: the cable can be in the 125 ° C ambient temperature for long-term work, alternative to the temperature 125 ° C of the low-smoke halogen-free flame-retardant cable to use. Corrosion resistance: the cable insulation is made of inorganic mineral material, which can be laid without any additional measures. High mechanical strength: YTTW (BTTE), NG-A (BTLY), RTTZ mineral insulated fire protection cable sheath high melting point, under fire conditions with high resistance to mechanical impact. BBTRZ non-metallic flexible isolation fire protection cables due to the isolation layer material specificity, in the combustion conditions of the isolation layer inside the production of honeycomb-like rigid body structure, and can effectively resist the outside mechanical Impact. Length can be customized: As this series of products are flexible mineral insulated fireproof cable, can be bent into a circle on the cable tray packaging. This in essence determines the infinity of its manufacturing length. Therefore, the factory can supply according to the design length requirement provided by the customer. Stable insulation performance: Due to the unlimited length of the product, the product does not need to consider the length of the product in the installation of the joints brought about by insufficient length, the fewer the joints, the higher the insulation performance, and less susceptible to moisture. Electrical Characteristics:1. Rated Voltage: 450V-1000V; 2. Rated Current: Single-core 15A-1800A, Multi-core 16A-800A; 3. Insulation Resistance: Insulation Resistance ≥10,000MΩ-KM. for cable lengths of less than 100m, the Insulation Resistance is ≥ 10,000 MΩ-KM.
