    S107 (Formerly S13) BU(i) 250 V

    Applications

    These cables are fire resistant, flame retardant, low smoke and halogen free, 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.

    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.

    Outer Sheath : Halogen free thermosetting compound, SHF2, coloured grey (blue for intrinsically safe).
