LSZH cables - Low smoke zero halogen flame retardant cable
Low smoke zero halogen flame retardant cable

Low smoke halogen-free flame retardant cable is difficult to fire and has the ability to stop or spread, once on fire, it has no halogen, low smoke, non-toxic, non corrosive and other characteristics, which is suitable for high-rise buildings, hotels, hospitals, subway, tunnel, nuclear power plant, power plant, mining, petroleum, chemical etc.
 
Low smoke halogen free flame retardant cable in addition to meet the characteristics of low smoke halogen free flame retardant cable, it can also meet the ability of power supply in fire conditions. Mainly used for fire alarm, fire fighting equipment, smoke exhaust equipment, and emergency channel transport, lighting and other emergency facilities  supply line with need fireproof place.
 
(1), low smoke halogen-free cable flame retardant rating:
According to the test conditions specified in GB/T18380.3-2002, low smoke halogen-free flame retardant grade cable is divided into A, B, C, D four grades.
 
Flame retardant grade Fire temperature Time of fire Volume of bundles laying cable non-metallic materials Carbide height Self-extinguishing time
A ≥815℃ 40min ≥7 L/m ≤2.5 m ≤1h
B ≥815℃ 40min ≥3.5 L/m ≤2.5 m ≤1h
C ≥815℃ 20min ≥1.5 L/m ≤2.5 m ≤1h
D ≥815℃ 20min ≥0.5 L/m ≤2.5 m ≤1h
 
(2) low smoke halogen free cable insulation adopts halogen free crosslinked polyethylene, the sheath use halogen free polyolefin materials, so all of the material that is composed of a cable does not contain halogen. The amount of smoke when cable burning release is very few, it does not produce acid, strong toxic gases, low toxicity.
 
Low smoke zero halogen cable type consists of two parts, combustion characteristic code and cable type:
 
Combustion characteristic code:
Flame retardant grade A: ZA
Flame retardant grade B: ZB
Flame retardant grade C: ZC
Flame retardant grade D: ZD
Fire-resistant: N
Low smoke low halogen: WD
 
Use code:
Power cable: omit
Control cable: K
Wiring: B
 
Materials code:
Copper conductor: omit
XLPE insulation: YJ
Polyolefin sheath: Y(E)
