    K20 & L120 LSZH Armoured F/FTP Cat6 Cables

    Application

    The cables are designed for high speed data transmissions, and are suitable for installations in cable trays or on hooks.

    Standard

    • RATP CAT6-K20 (for K20 cable)
    • FRANCE TELECOM S31-10/20 & NF C 93.531-6/7 (for L120 cable)

    Cable Construction

    • Electrical Characteristics at 20℃Conductors: Class 1 AWG23 solid copper conductor (for K20 cable); 0.6mm annealed copper conductor (for L120 cable).
    • Insulation: Solid polyethylene (for K20 cable); Foam skin (cellular PE + solid PE) (for L120 cable).
    • Cabling Element: Two conductors are twisted together to form a pair (for K20 cable); Four conductors are twisted together to form a quad (for L120 cable).
    • Core Wrapping (for L120 cable): Non-hygroscopic plastic tape with overlapping.
    • Individual Screen (for K20 cable): Alu/polyester shield on each pair.
    • Overall Screen: Alu/polyester shield.
    • Drain Wire: Tinned copper drain wire, 0.5mm nominal diameter.
    • Inner Sheath (for K20 cable): LSZH.
    • Armour (for K20 cable): Galvanized steel braid armour.
    • Outer Sheath: LSZH.
    • Optional

    • Armoured L120 Cables: Tinned copper braid armoured cables can be offered upon request.
