Advantages and disadvantages of low smoke halogen-free cable

Date: Apr 27th,2024

In recent years, the proportion of fire accidents caused by power cable faults has been increasing in recent years. Therefore, it is more and more important to use low-smoke halogen-free cables with the advantages of halogen-free, high flame retardant, low smoke and low toxicity. This requires a thorough and accurate understanding of smokeless, halogen-free cables. This is the first condition for the correct selection of cables. So what are the advantages and disadvantages of low-smoke halogen-free cables?

Halogen-free material

The use of green environmental protection insulation layer, sheath and special oxygen blocking material, not only has excellent electrical properties, physical and mechanical properties, but also ensures that the product does not contain halogen. At the same time, it avoids the toxic substances generated when the cable material accidentally burns the traditional PVC wire.

Environmental protection

The insulation and sheath do not contain lead, cadmium and other heavy metals harmful to human body. The cable will not contaminate soil or water during use and disposal. Compared with traditional cables, it is more environmentally friendly. Low-smoke halogen-free cables are also known as environmental protection cables, which can be seen in their role in environmental protection.

Highly flame retardant

Environmental protection cables are not easy to burn in the event of a fire, which can prevent the spread of fire and the spread of disasters after the fire. Especially in modern cities, high-rise buildings, modern material products, once a fire, rescue is very difficult. Low-smoke halogen-free cables can increase rescue time and reduce the harm of toxic gases to the human body.

Low smoke, low toxicity

Due to the use of new special coatings that do not pollute the environment, no toxic gases are produced during manufacturing, use and combustion, and acid gas emissions are extremely low, causing little harm to personnel and equipment. Low-smoke halogen-free cables should be used and promoted, especially in densely populated cities.

Disadvantages of low-smoke halogen-free cable:
The disadvantage of low-smoke halogen-free cables is that they have a higher price and a very low popularity than general PVC cables. Low-smoke halogen-free cables are environmentally friendly, but their raw materials and engineering costs are more expensive than ordinary PVC cables. In addition, ordinary PVC cables and polyethylene cables have excellent electrical conductivity and mechanical properties, so low-smoke halogen-free cables cannot completely replace ordinary cables, so they are not widely used.
But now, low-smoke halogen-free cables are more and more widely used in high-rise buildings, stations, subways, airports, hospitals, large libraries, gymnasiums and homes. In densely populated places such as families, hotels, hospitals, office buildings, schools, and shopping malls, with the enhancement of people's awareness of fire prevention, low-smoke halogen-free cables are more and more applied in our lives.
