Applications

These S1 or S1/S5 RFOU(i) 250V NEK606 Water Blocked Offshore Marine cables are partially water blocked, flame retardant, low smoke, halogen free and mud resistant, used for instrumentation, communication, control and alarm systems.Offshore instrumentation 250 V individually screened cable. Heavy duty, mud resistant, instrumentation cables for Offshore applications. Halogen free, flame and fire non propa-gator. Excellent resistance to oils, abrasion, petrochemical fluids, moisture and salt water. Based on IEC 60092-376 and NEK TS 606. These cables offer excellent performance in the harsh environments encountered offshore. Suitable for fixed installations in vessels and oil rigs.

Standards

IEC 60092
IEC 60332 
NEK 606 

Construction

Conductors: Circular tinned annealed stranded copper wire to IEC 60228 class 2.
Insulation: Halogen free EPR compound.
Twinning: Colour coded cores twisted together.
Filler: Water blocking fillers, if required.
Individual Shielding: Each pairs/triples are screened by copper backed polyester tape in contact with a stranded tinned copper drain wire and wrapped with polyester tape. Pairs/triples are numbered with numbered tape or by numbers printed directly on the insulated conductors.
Filler: Water blocking fillers, if required.
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.
Water Blocking Elements: Water blocking tape and strings for providing longitudinal water tightness.
Inner Sheath: Halogen free thermosetting compound, SHF2 (for TYPE S1). Halogen free MUD resistant thermosetting compound, SHF MUD (for TYPE S1/S5), coloured grey (blue for intrinsically safe).
Outer Sheath: Polyurethane for providing transversal water tightness, PE is optional,but can not meet low smoke standard.
