What you may not know about low-smoke halogen-free cables
Traditional wires and cables are mostly made of halogen-containing materials, such as polyvinyl chloride (PVC). Once a fire occurs, these cables will become the source of highly toxic and dense smoke. When burning, they will release a large amount of hydrogen halide gas, such as hydrogen chloride, which is not only highly corrosive, but also irritates the respiratory tract and makes it difficult for people to breathe. At the same time, the thick smoke seriously reduces the visibility at the fire scene, making it difficult for trapped people to find escape routes and for rescuers to carry out rescue work. So, is there a kind of wire and cable that can reduce these hazards in the event of a fire? This has to mention low-smoke halogen-free wires and cables.
Low smoke and halogen-free wire and cable, from the name you can see its two key characteristics: low smoke and halogen-free. It refers to wire and cable that does not contain halogen (such as chlorine, bromine and other halogen elements) in the constituent materials. It produces less smoke and dust when burned, that is, the light transmittance is higher, and the corrosion of the combustion products is lower, which can fully guarantee the safety requirements of users when using it. Because it causes little harm to the environment when used, it is often called clean cable or environmentally friendly cable.
When low-smoke halogen-free wires and cables encounter flames, they will not produce "thick smoke" like traditional cables. During the combustion process, it will only produce a light mist, and the visible distance can reach more than 60 meters, which provides a clearer view for people to escape and rescue in the fire. In terms of toxicity, it does not contain any toxic substances, unlike halogen-containing cables that release highly toxic gases such as hydrogen chloride when burning. In addition, low-smoke halogen-free wires and cables also have good flame retardant properties, which effectively prevent the spread of flames.
One of the biggest highlights of low-smoke halogen-free wires and cables is that they are green and environmentally friendly. It abandons halogen-containing materials in the production process and eliminates the use of toxic and harmful substances from the source. Therefore, no toxic gases such as hydrogen halides are released during combustion, which greatly reduces the toxic hazards in fires. Low-smoke halogen-free wires and cables, with their green and environmentally friendly, excellent flame retardant, long life and many other advantages, bring more reliable security and a cleaner environment to our lives. It is not only the result of scientific and technological progress, but also an important choice for us to pursue a high-quality life. Choosing low-smoke halogen-free wires and cables is choosing a peace of mind and a responsibility for the future.
