S3 or S3/S7 BFOU(i) 250V S3 or S3/S7 BFOU(i) 250V

S3 or S3/S7 BFOU(i) 250V 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.
  • 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.
  • Bedding : Halogen free compound.
  • Armour : Tinned copper wire braid.
  • Outer Sheath : Halogen free thermosetting compound, SHF2 (for TYPE S3). Halogen free MUD resistant thermosetting compound, SHF MUD (for TYPE S3/S7), coloured grey (blue for intrinsically safe).
