Cable manufacturers introduce low-smoke halogen-free wires to you
In daily life, we frequently use various electrical appliances every day, from lighting fixtures to large household appliances, electricity has become an indispensable part of our lives. However, have you ever stopped to think about whether the wires that power these appliances at home are safe?
Maybe you think that the wires have been hidden in the walls and wire troughs, and the appearance looks intact, so there is no problem. But in fact, the safety hazards of wires are often hidden in places that are not easy to detect. Line aging is one of the common hidden dangers. As the use time increases, the insulation layer of the wire will gradually age and break, just like a piece of clothing that has been worn for a long time, it becomes shabby and loses its due protection, which can easily lead to short circuits and fires. In the face of these potential threats, we must pay attention to the safety of wires. The emergence of low-smoke halogen-free wires provides us with a safer and more reliable choice.
In simple terms, low-smoke halogen-free wires refer to wires that do not contain halogens (such as chlorine, bromine and other halogen elements) in their constituent materials, produce less smoke and dust when burned, and have less corrosive combustion products. Compared with traditional wires, low-smoke halogen-free wires have significant differences in materials and characteristics. Traditional wires mostly use polyvinyl chloride (PVC) as insulation and sheath materials, which release a large amount of toxic gases and thick smoke when burned. The insulation and sheath of low-smoke halogen-free wires are made of special halogen-free materials. These materials not only have good electrical properties, but also greatly reduce the generation of toxic gases and smoke when a fire occurs, buying more time for people to escape and rescue.
Ordinary wires mostly use polyvinyl chloride (PVC) as the insulation layer, which contains halogen components. Once a fire occurs, ordinary wires will produce a lot of black smoke and toxic gases such as hydrogen chloride and carbon monoxide when burning. These toxic gases will not only cause serious corrosion to surrounding equipment, but also spread rapidly at the fire scene, hindering people from escaping and bringing great difficulties to rescue work. Moreover, even if there is no fire, PVC materials may slowly soften under high temperature conditions during long-term use and release trace amounts of harmful substances, causing potential pollution to the indoor environment.
From the perspective of combustion characteristics, low-smoke halogen-free wires are very different from ordinary wires. When a fire unfortunately occurs, ordinary wires have relatively weak flame retardant properties and spread very quickly, and the fire can easily spread rapidly in a short period of time. At the same time, it will release a large amount of thick smoke, instantly reducing the visibility of the fire scene, making it difficult for people to identify the direction of escape, and increasing the risk of being trapped and casualties. Moreover, the highly toxic gases such as hydrogen chloride released by the combustion of ordinary wires will cause strong irritation and damage to the human respiratory tract and eyes, seriously threatening life safety.
Low smoke halogen-free wire performs well. It has strong flame retardancy and can effectively suppress the spread of fire, buying precious time for people to escape and fire rescue. During the combustion process, the smoke concentration produced by low smoke halogen-free wire is extremely low, which has little impact on visibility, greatly increasing the possibility of escape. In addition, it only releases a small amount of CO and almost no other toxic gases, reducing the harm to the human body and providing a safer environment for people in the fire.
From the perspective of initial cost, low smoke halogen-free wire is about 20%-30% higher than ordinary PVC wire due to the use of more advanced materials and more complex production processes, which makes some cost-sensitive consumers hesitate when choosing. However, if we analyze it from the perspective of long-term benefits, we will find that low smoke halogen-free wire is actually more cost-effective. Moreover, low smoke halogen-free wire can reduce the generation of toxic gases and smoke in fires, reducing secondary losses caused by fires.
Low smoke halogen-free wires have become an ideal choice for wires in modern life with their excellent environmental performance, outstanding safety protection, all-round performance advantages and a wide range of applicable scenarios. They not only protect our family safety and the health of our family members, but also play a key role in many public places and important fields, reducing the risk of fire and ensuring the safety of life and property.
