Application

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)

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.
