What Are Low Smoke Zero Halogen Cables?

When it comes to cables, we all know that they are the linear cables that transmit electricity for our lives. They are of great help to our lives. However, cables are also divided into many types, and different types of cables have different functions and characteristics. Among them, low smoke zero halogen cables are one of the more special cables.Get more news about Lszh Cable,you can vist our website!

1. What are low smoke zero halogen cables?
Low smoke zero halogen cables, also known as green cables, non-polluting cables, clean cables, etc., referring to the environmentally friendly cables that do not produce toxic fumes (such as hydrogen halide, carbon monoxide, carbon dioxide, etc.) when they are burned. They are made of rubber materials without containing halogen (F, Cl, Br, I, At), lead, cadmium, chromium, mercury and other environmental substances.

The so-called low smoke emphasizes that they will not produce a lot of dense smoke after burning, While halogen-free means that some chemical substances, such as chlorine and fluorine, are not added in the process of making cables, because these chemical substances give off toxic gases that are toxic to the human body when they are burned. Therefore, the low smoke zero halogen cables are relatively environmentally friendly cables.
2. The design reasons for low smoke zero halogen cables:
As we all know, fires often break out in society and many people lost their lives in fires. However, what we do not know is that in those fires, many people were not burned to death by the fire, but were basically smothered by the smoke of the fire. Therefore, it is necessary for low smoke zero halogen cable manufacturers to design cables that do not produce dense smoke to harm human health, while the low smoke zero halogen cables are exactly the product of this requirement, and their appearance is also to better protect our health and lives.

3. The advantages of low smoke zero halogen cables are as follows:
1. The total halogen value in the cables does not exceed 50ppm.

2. The amount of hydrogen halide gas produced after combustion is less than 100 ppm.

3. The pH value of the hydrogen halide gas produced after combustion is ≥4.3 after being dissolved in water, which is weakly acidic.

4. After being burnt in a sealed container, the light transmittance of the product exceeds 60% through the beam.

5. Pb (lead) <90ppm, Cd (cadmium), Cr6 (chromium), Hg (mercury), PBBs (polybrominated biphenyls) and PBDEs (polybrominated diphenyl ethers) are all less than 5ppm.
