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