Five core 16mm2 distribution cable for tunnels, stations, hospitals and other enclosed spaces where a fire must not turn the escape route into a smoke-filled shaft. The LSZH oversheath contains no halogen and no PVC, so combustion produces very little hydrogen chloride gas and light transmittance stays above the sixty percent threshold in the IEC 61034 test. Copper conductors keep the resistance low, while the XLPE insulation tolerates a 90 C conductor temperature without softening.
The low smoke halogen free sheath is a compounded thermoplastic polyolefin, extruded in a single pass over the copper tape screened assembly. It is tough enough for tray and trifor routing, resists oil and cleaning chemicals, and stays flexible at low winter temperatures. For metro projects we supply matching test documentation: smoke density, acid gas, flame propagation and oxygen index, all traceable to the drum number.
Because a five core cable carries three phases, neutral and earth in one jacket, the contractor needs fewer supports and fewer drawing changes in congested tunnel sections, which is exactly where LSZH cable earns its cost back.

The compound is checked for halogen content, pH and conductivity before extrusion, and finished cable is spark tested and routine voltage tested at 3.5 kV. Third party reports for smoke density and acid gas are issued per batch, so your fire safety consultant can verify the low smoke halogen free claim without sampling delays. The low smoke halogen free LSZH sheath is extruded over the screened 5x16mm2 copper cores in a single pass, so the finish stays tight at bends and inside trunking.
Ordering low smoke cable for a tunnel or station package usually starts with a fire strategy document. Send us the circuit list and we will map each feeder to the right five core 16mm2 assembly, then supply one drum plan per area so the installer is not cutting cable in a smoke logged corridor. Colour coding of cores, drum labels and third party test packs are prepared to match your handover requirements, and shorter coils are available for panel and riser work.
Q: What exactly does low smoke halogen free mean on this cable?
A: It means the sheath contains no halogenated polymer, so smoke is light and the gas released is not corrosive. We verify both properties with IEC 61034 and IEC 60754-2 test reports.
Q: Can the 5x16mm2 cable be used outdoors?
A: Yes, the LSZH sheath is UV stabilised for outdoor tray and duct work, though for long exposed runs above ground we recommend a black UV resistant variant.
Q: Is the earth core the same size as the phase cores?
A: On this five core 16mm2 cable all five cores are 16mm2, so the protective conductor matches the phase section for easy fault loop calculations.
Q: Do you supply cable with CPR or EN 13501 classification?
A: We can arrange additional testing for CPR class Cca or B2ca on request; lead time is normally three to four weeks for the sample submission.
Q: How is the five core 16mm2 cable packed for a station package?
A: Normally 1000 m drums for main runs and 100 m coils for panels and risers, all labelled with drum number, length and the low smoke halogen free test report reference.
