MV RFOU P19/P21 12/20KV (NEK606) 

Applications

These P19/P21 RFOU 12/20KV NEK606 Water Blocked Offshore Marine cables are partially water blocked, flame retardant, low smoke, halogen free and mud resistant, used for fixed installation for medium voltage power. Offshore power Medium Voltage cables. Medium voltage heavy duty, mud resistant cables for offshore applications. Halogen free, flame and fire non propagator. Excellent resistan-ce to oils, abrasion, petrochemical fluids, moisture and salt water. Based on IEC 60092-354 and NEK TS 606. Suitable for fixed installations in vessels and oil rigs.

Standards

IEC 60092
IEC 60332 
NEK 606 

Construction

Conductors: Circular tinned annealed stranded copper to IEC 60228 class 2.
Conductor Screen: Semi conducting material.
Insulation: Halogen-free EPR. XLPE can be offered as an option (for TFOU cable).
Insulation Screen: Semi conducting material and tinned copper wire braid.
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 P19), or halogen free mud resistant thermosetting compound, SHF MUD (for TYPE P19/P21), coloured red.
Outer Sheath: Polyurethane for providing transversal water tightness, PE is optional,but can not meet low smoke standard.
 

Optional

P20 or P20/P22 RFOU/TFOU 18/30(36) kV.
