Water Blocked S4 or S4/S8 BFOU(c) 250V

Applications

Water Blocked S4 or S4/S8 BFOU(c) 250Vcables are fire resistant, flame retardant, low smoke, halogen free and mud resistant, used for instrumentation, communication, control and alarm systems.

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 annealed stranded copper wire to IEC 60228 class 2.
  l???? Insulation: Mica tape + Halogen free EPR compound.
  l???? Twinning: Colour coded cores twisted together.
  l???? Filler: Water blocking fillers, if required.
  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???? 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 (for TYPE S4). Halogen free MUD resistant thermosetting compound, SHF MUD (for TYPE S4/S8), coloured grey (blue for intrinsically safe).
  l???? Outer Sheath: Polyurethane for providing transversal water tightness, PE is optional,but can not meet low smoke standard.
