LSZH Flame Retardant Marine Cable
A halogen-free construction that limits smoke density and acid gas emission, so a fire in an accommodation space does not become a smoke event.
Construction and performance
In an enclosed space the danger in a cable fire is not the flame, it is the smoke and the acid gas. Halogenated sheaths release hydrogen chloride, which is corrosive to electronics and toxic when inhaled, and dense smoke removes the visibility that an evacuation depends on. LSZH compounds are formulated to meet the IEC 60754 halogen limits and the IEC 61034 smoke-density limit while still passing IEC 60332 flame propagation. On a passenger vessel the specification is normally confined to the zones where SOLAS requires it.
Construction
- Tinned copper conductor, class 2
- XLPE or LSZH insulation
- LSZH sheath, halogen free
- Smoke density to IEC 61034-2
- Halogen gas emission to IEC 60754-1 / -2
- Flame propagation to IEC 60332-1-2 and IEC 60332-3-22
Applications
- Passenger and cruise vessels
- Accommodation and public areas
- Offshore living quarters
- Tunnels and enclosed spaces

What to confirm before ordering
Is LSZH the same as halogen free?
Does LSZH cable cost more?
Can LSZH and PVC cable share a tray?
Standards & type approval
IEC 60092-353, IEC 60092-359, IEC 60754-1/-2, IEC 61034-2, IEC 60332-3. Classification-society type approval available; SOLAS fire-safety requirements apply to the installation zones rather than to the cable alone.
