    S104 (Formerly S4 or S4/S8) BFOU(c) 250V

    Applications

    These cables 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 60092-360

    IEC 60331-21

    IEC 60332-1

    IEC 60332-3-22

    IEC 60754-1,2

    IEC 61034-1,2

    NEK 606:2016

    Construction

    Conductors : Circular tinned annealed stranded copper wire to IEC 60228 class 2 or class 5.

    Insulation : Mica tape + Halogen free EPR compound or Mica tape + XLPE.

    Twinning : Colour coded cores twisted together.

    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.

    Bedding : Halogen free compound.

    Armour : Tinned copper wire braid.

    Outer Sheath : Halogen free thermosetting compound, SHF2 (formerly TYPE S4). Halogen free MUD resistant thermosetting compound, SHF MUD (for formerly TYPE S4/S8), coloured grey (blue for intrinsically safe).
