LSZH Cable

LSZH Cable – Low Smoke Zero Halogen Cable for Safer, Greener Installations

LSZH cable (Low Smoke Zero Halogen cable), also known as zero halogen cable, is an environmentally friendly power cable designed to minimize the release of harmful substances during combustion. Unlike traditional PVC cables, LSZH cables emit minimal smoke and no toxic halogen gases, making them ideal for use in enclosed or densely populated spaces where fire safety is critical.

✅ What Is LSZH Cable?

LSZH (Low Smoke Zero Halogen) cables are constructed with a halogen-free thermoplastic sheath that contains no fluorine, chlorine, bromine, iodine, astatine, or heavy metals like lead, cadmium, or mercury. In the event of a fire, these cables emit little smoke and no corrosive or toxic gases, significantly reducing harm to people and equipment.

🔍 Main Features of LSZH Cables

• Halogen Content: ≤50 PPM (per PREN 14582)

• Acid Gas Emission: <100 PPM (per EN 5067-2-1)

• pH Value: ≥4.3 (non-corrosive, per EN 50267-2-2)

• Light Transmittance After Combustion: ≥60% (per EN 50268-2)

• Heavy Metals: Pb <90 PPM; Cd, Cr⁶⁺, Hg, PBBs, PBDEs <5 PPM

These cables are compliant with international environmental and fire safety standards.

🔧 Applications of Low Smoke Zero Halogen Cable

Thanks to their flame-retardant, low-smoke, and non-toxic properties, LSZH cables are widely used in:

• Nuclear power plants

• Subway and railway systems

• Telephone and data centers

• High-rise buildings and hotels

• Hospitals and public venues

• Military installations

• Oil and gas platforms

• Telecommunication and broadcast facilities

Ideal for any location with limited ventilation or high occupancy.
