NEK606 Water Blocked Offshore & Marine Cables

Water Blocked S16 BFOU-HCF(c) 250 V

Applications

• These cables are partially water blocked, fire resistant, flame retardant, low smoke and halogen free, used for emergency instrumentation, communication, control and alarm systems that need to be operational during a 1100°C hydrocarbon fire.

Standards

• IEC 60092-376	IEC 60092-351
  IEC 60092-359	IEC 60332-1
  IEC 60332-3-22	IEC 60754-1,2
  IEC 61034-1,2	NEK 606:2004
  IEC 60331-21	VG 95218 part 29?

Construction

• l??? Conductors: Circular tinned stranded copper wire to IEC 60228 class 2.
  l??? Insulation: Mica tape + Halogen free EPR compound.
  l??? Twinning: Colour coded cores twisted together.
  l??? 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.
  l??? Filler: Water blocking fillers, if required.
  l??? Bedding: Halogen free compound, PETP wrapping tape will be applied over the bedding, if required.
  l??? 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.
  l??? Inner Sheath: Halogen free thermosetting compound, SHF2.
  l??? HC-fire protection: Extruded thermoplastic fire protection compound.
  l??? Taping: Lapped glass fibre tape.
  l??? Outer Sheath 1: Flame retardant halogen-free thermoplastic compound, type SHF1, coloured grey (blue for intrinsically safe).
  l??? Outer Sheath 2: Polyurethane for providing transversal water tightness, PE is optional,but can not meet low smoke standard.
