|
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.
