K20 & L120 LSZH Armoured F/FTP Cat6 Cables

 

Applications :

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

Standards :

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

 

Construction :

  • 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.
