Flame Retardant _ LSZH Cable
Farwalk’s Flame Retardant LSZH Cables are the essential building blocks for safe, high-density public infrastructure. Engineered to self-extinguish and halt the spread of fire along cable trays, these cables feature Low Smoke Zero Halogen (LSZH) materials that eliminate deadly toxic fumes and blinding black smoke, ensuring safe human evacuation and protecting sensitive electronic assets.
Manufactured with premium plain copper conductors and high-thermal-capacity XLPE insulation. The inner bedding and outer sheath are extruded from specialized Low Smoke Zero Halogen (LSZH) polyolefin compounds. The cables are formulated to pass severe vertical bundled flame propagation tests, guaranteeing they will not act as a conduit for fire.
The standard requirement for power distribution in densely populated or enclosed spaces where fire safety is paramount. Applications include: Subway networks, airport terminals, data centers, hospitals, high-rise residential towers, and enclosed industrial control rooms.
• Voltage Rating: 0.6/1kV
• Flame Retardance: IEC 60332-1, IEC 60332-3 (Cat A/B/C)
• Halogen Free: IEC 60754-1/2
• Low Smoke Emission: IEC 61034-1/2
• Insulation: XLPE (90°C)
• Sheath: LSZH (Thermoplastic)
• Conductor: High-conductivity stranded plain Copper (Cu).
• Insulation: Cross-linked Polyethylene (XLPE) for high continuous operating temperature (90°C) and superior dielectric strength.
• Inner Bedding: Flame-retardant, halogen-free compound.
• Outer Jacket: Low Smoke Zero Halogen (LSZH) polyolefin compound, highly resistant to flame propagation, and emitting zero toxic gas during combustion.
• Flame Spread Arrestor: Engineered to strictly inhibit the propagation of fire along cable trays or building shafts, passing the rigorous IEC 60332-3 bundled flame tests.
• Life Safety Assured (LSZH): In the event of a fire, the jacket emits near-zero smoke and absolutely no corrosive halogen gases (like HCl), ensuring clear escape routes for personnel and preventing acid damage to sensitive electronics.
• High Electrical Efficiency: The XLPE insulation allows for higher current carrying capacities compared to standard PVC, optimizing spatial requirements in crowded electrical ducts.
• Certified Compliance: Our LSZH cables are thoroughly tested to IEC 60754 and IEC 61034 standards, providing verifiable safety for public and commercial life-safety audits.
• Asset Protection: By eliminating corrosive acid gas emissions during a fire, Farwalk LSZH cables prevent secondary damage to expensive IT servers and telecommunications hardware.
• Scalable Supply: Available in configurations ranging from 1.5mm² control wires to massive 400mm² industrial power feeders.
Comparison Logic: LSZH vs. Standard PVC
| Feature | Flame Retardant LSZH | Standard PVC | Fire Resistant (Mica) |
| Flame Propagation | Self-extinguishing (Stops spread) | Burns and spreads rapidly | Self-extinguishing |
| Smoke Emission | Near Zero (Clear visibility) | High (Thick black smoke) | Near Zero |
| Halogen Gas Release | Zero (No toxic HCl gas) | High (Highly toxic & corrosive) | Zero |
| Maintains Circuit in Fire? | No (Insulation melts) | No (Burns rapidly) | Yes (Survives 3 hours) |
