What Are the Characteristics of Low-Smoke Halogen-Free Cables?

Whether it is food or daily necessities, the concept of green has deeply penetrated people's hearts. More and more people choose to use environmentally friendly products. In many places, cable engineering will be used for fire protection, monitoring, alarm and other low smoke and halogen-free cables. Generally, people refer to them as environmentally friendly cables, not specifically low smoke and halogen-free cables. So what is low smoke and halogen-free cable?

What is low smoke and halogen-free cable?

As the name suggests, low smoke and halogen-free cables are low in smoke, which reduces the production of harmful substances during combustion and does not contain halogens. It is well known that halogens are toxic gases to the human body. Halogen-free cables no longer release toxic gases. Usually, this situation refers to cables in the event of a fire. Low smoke and halogen-free cables can also be called environmentally friendly cables. Low smoke and halogen-free cables are commonly used in hospitals and places with strict environmental sanitation requirements.

Characteristics of low smoke and halogen-free cable

Low smoke and halogen-free cables use green insulation, sheathing, and unique oxygen barrier materials, which not only have good electrical and physical mechanical properties, but also ensure that the products do not contain halogens and do not cause "secondary pollution" during combustion, avoiding the formation of carcinogenic "dioxin" substances in traditional PVC wires when burned.

Low smoke and halogen-free cables have high flame retardancy: low smoke and halogen-free cables meet the high requirements of building fire protection, and the cables are not easy to burn when exposed to fire, which can prevent the spread of flames and the escalation of disasters.

Low smoke and halogen-free cables are low in toxicity: the insulation and sheathing do not contain harmful heavy metals such as lead and cadmium, and they will not pollute the soil and water during cable use and waste disposal. After a short toxicity test, the rats are unharmed under the specified experimental conditions.

Low smoke and halogen-free cables do not produce corrosive gases: using a new type of unique coating material, it is environmentally friendly and does not produce HCL and other gases during production, use, and combustion. The emission of acidic gases is extremely low, causing minimal harm to personnel, equipment, and instruments, showing its more environmentally friendly characteristics.

Low smoke and halogen-free cables are waterproof and UV resistant: using special molecular structure green and environmentally friendly materials to ensure ultra-low water absorption. Special UV absorbers make the product have good UV resistance, ensuring the safety and extending the service life of such products. The first company to introduce the name "environmentally friendly cable" was a Japanese company, which formulated the product standard as the FN ecological cable standard. Western countries such as the United Kingdom have also developed advanced standards for environmentally friendly cables, which have gradually been promoted worldwide.

Low smoke and halogen-free cables have high transparency: the smoke generated by burning cables is thin, which is conducive to personnel evacuation and firefighting. The light transmittance of the product is above 40%, which is much higher than that of traditional flame-retardant cables.
