Instructions for low-smoke and halogen-free cables
LSZH cables can be divided into LSZH series and LSZH series.
Low-smoke halogen-free cables are produced by our company in accordance with French standards RCCE and NF series standards, national standards GB/T18380, GB/T19216, GB/T17651, GB/T17650 and international standards.
The low-smoke, halogen-free, flame-retardant cable is difficult to catch fire and has the ability to prevent or delay the spread of flames. Moreover, once it catches fire, it has the characteristics of halogen-free, low-smoke, non-toxic, non-corrosive, etc., suitable for high-rise buildings, hotels, hospitals, etc. , Subways, nuclear power plants, tunnels, power plants, mines, petroleum, chemical industries, etc.
In addition to meeting the characteristics of low-smoke, halogen-free and flame-retardant cables, low-smoke halogen-free fire-resistant cables can also meet line power supply capabilities under fire conditions. Mainly used in fire alarm, fire fighting equipment, smoke exhaust equipment, emergency channel transportation, lighting and other emergency facilities in the power supply line where fire resistance is required.
Flame retardant grades of low-smoke and halogen-free cables
According to the test conditions specified in GB/T18380.3-2008, the flame retardant grades of low-smoke halogen-free cables are divided into four grades: A, B, C, and D. If the flame retardant grade is not indicated, it will be regarded as B grade.
