Applications

These S4 or S4/S8 BFOU(c) 250V NEK606 Water Blocked Offshore & Marine cables are fire resistant, flame retardant, low smoke, halogen free and mud resistant, used for instrumentation, communication, control and alarm systems. Suitable for fixed installations in vessels and oil rigs, assuring the highest level of safety, security and reliability.

Standards

IEC 60092
IEC 60332
NEK 606

Construction

Conductors: Circular tinned annealed stranded copper wire to IEC 60228 class 2.
Insulation: Mica tape + Halogen free EPR compound.
Twinning: Colour coded cores twisted together.
Filler: Water blocking fillers, if required.
Collective Shielding: Pairs/triples are layed up and collectively screened by copper backed polyester tape in contact with a stranded tinned copper drain wire. Pairs/triples are numbered with numbered tape or by numbers printed directly on the insulated conductors.
Bedding: Halogen free compound, PETP wrapping tape will be applied over the bedding, if required.
Armour: Tinned copper wire braid, PETP wrapping tape will be applied over the braiding, if required.
l Water Blocking Elements: Water blocking tape and strings for providing longitudinal water tightness.
Inner Sheath: Halogen free thermosetting compound, SHF2 (for TYPE S4). Halogen free MUD resistant thermosetting compound, SHF MUD (for TYPE S4/S8), coloured grey (blue for intrinsically safe).
Outer Sheath: Polyurethane for providing transversal water tightness, PE is optional,but can not meet low smoke standard.
