How important is halogen-free wire?

Low-smoke halogen-free electronic cables are also called green cables, pollution-free cables, clean cables, etc.Refers to environmentally friendly cables that do not produce toxic fumes such as hydrogen halide, carbon dioxide, etc.During combustion.They are made of rubber materials and contain no halogens (fluorine, chlorine, bromine, iodine, arsenic), lead, cadmium, chromium, mercury and other environmental substances.
The so-called low smoke emphasizes that no large amount of smoke will be produced after burning; halogen-free means that chemical substances such as chlorine and fluorine will not be added during the process of making cables, because these chemicals will release toxic gases when burning and cause toxicity to human body.Therefore, the low smoke halogen free electronic cable is an environmentally friendly cable.
Low smoke halogen-free wire material can reduce the toxic and corrosive gases produced during combustion.Low-smoke halogen-free materials are commonly used in poorly ventilated environments, such as airplanes, train carriages, or ships.Low-smoke halogen-free materials are also widely used in the railway industry, because there are high-voltage lines or signal lines underneath the railway to transmit train locations.
Halogen-free wire materials can also reduce the accumulation of toxic gases when the line is damaged by fire or short circuit.Made of polyethylene, polyvinyl chloride or thermoplastic polyurethane.When a fire occurs, chlorine-containing plastics release toxic gases.However, low-smoke halogen-free materials do not release hydrogen halide or other acids when ignited.
As we all know, there are many fires in society and many people lost their lives in them.What we don't know, however, is that many people in those fires were not burned down by the fire, but were basically overwhelmed by it.
Therefore, it is necessary for technicians to design cables that do not produce smoke or harm human health. Halogen-free electronic cables are the products of this requirement, and they appear to better protect our health and safety.
Due to the performance characteristics of halogen-free electronic lines, they are widely used in large-scale engineering and high-tech fields, such as railways, Metro stations, automobiles, etc. In daily life, they are widely used in nuclear power stations, Metro stations, telephone switches and computer control sites, high-rise buildings, hotels, radio and television stations, important military facilities and oil platforms, and places where people are relatively concentrated.
