Flame-retardant cables are special cables that have self-extinguishing properties when a fire occurs. After being ignited under specified test conditions, the flame will not continue to spread after the fire source is removed. The residual flame and residual burning can be extinguished by themselves within a limited time, which can effectively slow down the spread of the fire and ensure the evacuation of personnel and property safety. The core characteristic of flame-retardant cables is not to ensure that the cables continue to operate in a fire, but to prevent the spread of fire even when burned, which has important fire safety significance.
Compared with ordinary cables, flame-retardant cables are similar in structure, but their insulation layer, sheath layer and other auxiliary materials are all made of flame-retardant materials, which have stronger fire-retardant properties. Wuxi Chenan Optoelectronics provides a wide variety of flame-retardant cables, covering two categories: halogen-containing flame-retardant cables and halogen-free low-smoke flame-retardant cables. Both support personalized customization and are suitable for mass production. Factory direct sales save customers procurement costs and are economical.
It is worth noting that halogen-containing flame-retardant cables may release corrosive halogen acid gases and produce irritating smoke when burning, which is not conducive to fire rescue. Therefore, in densely populated places such as schools, shopping malls, and hospitals, it is recommended to give priority to halogen-free, low-smoke, flame-retardant cables to reduce the risk of secondary disasters. In industrial work areas with a small population, you can flexibly choose according to the actual situation. It should be noted that although halogen-free, low-smoke cables are environmentally friendly, their electrical and mechanical properties are slightly inferior, and the bending radius needs to be appropriately increased when laying. Overall, flame-retardant cables not only have good safety, but also help reduce maintenance and accident costs. They are cost-effective and are an ideal choice for modern building electrical engineering.
