F1 QFCI - NEK 606 Offshore & Marine Cables

F1 QFCI Applications

These steel armoured optical fibre cables are flame retardant, low smoke, halogen-free and fire-resistant, used for communication and emergency systems that need to be operational during fire.

F1 QFCI Construction

Fibre Element : Loose tube core design.
Central Strength Element : Steel wire or fibre reinforced plastic (FRP).
Bedding : Halogen free and flame retardant thermoplastic compound.
Armour : Galvanized steel wire braid.
Outer Sheath : Halogen free and flame retardant, UV-stabilized, thermoplastic compound, SHF1.

Optional :

F4 QFCI-HCF : QFCI-HCF cables are consist of loose tube fiber element, steel wire or FRP central strength element, halogen-free and flame retardant thermoplastic bedding, galvanized steel wire braid armour, SHF1 sheath, HC-fire protection, fire-resistant tape and SHF1 outer sheath.
