Airport terminal wiring

Airport terminals are typically classified as Group D (assembly occupancy) under NBC 2016 Part 4 and require FR-LSH (IS 694:2010) minimum throughout occupied public areas per Cl. 4.15. AAI and DGCA project schedules typically upgrade to IS 17048:2018 LSZH for terminals where smoke and halogen limits are tender conditions.

LSZH delivers HCl < 0.5%, smoke transmittance ≥ 70%, and Oxygen Index > 30% per IS 17048:2018 — the safest choice for high-throughput public spaces.

Bunched cable installations on airport trays typically require IEC 60332-3-24:2018 Category C evidence — flame-spread limit 1.5 L/m fuel — submitted alongside single-cable test data per IEC 60332-1-2:2004. Category C is the appropriate level for grouped low-voltage cables in dense terminal trays.

National Cables' IS 17048:2018 HFFR cables are tested to this international standard; type-test reports are issued for institutional tender submission with the BIS licence reference (CM/L-8800227819).

BMS, fire alarm, and HVAC control circuits use screened multicore control cable based on IS 694:2010 Class 5 flexible — typically with aluminium foil + tinned drain-wire for EMI shielding where the discipline drawings call for it.

Class 5 fine-strand construction handles repeated bending during panel installation; the screen prevents EMI coupling with sensitive 4–20 mA loops, RTD inputs, and Modbus / BACnet signal lines that share trays with VFD and high-current power feeders. Specify foil + drain with single-point screen earthing per the EMC plan.

Airport equipment rooms and panel wiring use IS 694:2010 1100 V-class insulation rather than 600/1000 V cable to provide margin against motor-start surges and switching transients common in aviation infrastructure (jet bridges, baggage conveyors, HVAC AHU motors).

The same 1100 V production line manufactures the export H07Z-K (EN 50525-3-41) LSZH and H07V-K (IEC 60227-3) single-core wire — enabling consistent specification on cross-border terminal projects.

Yes. H07Z-K (EN 50525-3-41) LSZH single-core and H07V-K (IEC 60227-3) PVC single-core are produced from the same BIS-certified IS 17048:2018 and IS 694:2010 production lines and carry full international type-test documentation.

For airport projects in GCC, African, and European markets, these harmonised designations meet local specification practice without requiring cable redesign. Test certificates and material declarations are issued in tender-ready format.
