Low smoke halogen-free cable is a high-performance energy-saving and environmentally friendly products, characterized by wire conductors do not contain halogen, sulfur, nitrogen and other halides. This kind of cable has flame retardant properties and excellent insulation properties, and at the same time has good electrical conductivity. Low smoke halogen-free cable is mainly used in the field of building electrical, communications, etc., can work normally under various harsh conditions. Its insulation and sheath insulation is good, the insulation resistance is large, and the resistivity is between 0.5 and 35, which meets the combustion performance requirements of wires and cables specified in QC/T 1847-1999. Low smoke halogen-free cable is the use of special low smoke flame retardant material production of wire, because of its own characteristics, can meet the flame retardant requirements, high safety. Although there is a standard support and supervision system, there are still many questions about the flame retardant material itself.

The burning characteristic of low smoke halogen-free cable is one of the important indexes. When the cable is burning, the smoke concentration is low, only a light water mist is produced, and the visual distance is more than 60 meters. In addition, the low-smoke halogen-free cable does not emit toxic fumes when burned, such as hydrogen halides, carbon monoxide, carbon dioxide, etc., thus ensuring safety in the use environment.23I'm sorry.
Low-smoke halogen-free cables are used in a wide range of applications, including but not limited to airports, hospitals, large libraries and other places with high security requirements. These places have strict requirements on the safety and environmental protection of the wire, and the low smoke halogen-free cable is the ideal choice because of its excellent performance.
Internationally, agencies such as the National Electrical Code (NEC) and the National Fire Protection Association (NFPA) have clear requirements and standards for the safety and environmental protection of cables. Underwriters Laboratories (UL) offers a halogen-free (HF) and LSZH cable certification program based on IEC 62821 and IEC 60754 series standards to further ensure the quality and safety of low-smoke, halogen-free cables
