Construction

Conductors
Solid annealed bare or tinned copper sized 0.6/0.8/0.9mm as per class 1 of VDE 0295/IEC 60228

Insulation
Silicon Rubber compound as per DIN VDE 0266

Twisted Pairs
Insulated conductors are twisted into pairs with varying lay length to minimize crosstalk

Cabling Element
Twisted Pairs

Core Assembly
The twisted pairs are stranded to the core in layers

Core Wrapping
One or more non hygroscopic polyester tapes are helically or longitudinally laid with an overlap prior to sheathing

Screen
A laminated Aluminium/Polyester tape is placed in contact with solid copper 0.6mm or 0.8mm drain wire

Inner bedding (for armoured cables)
PE or LSZH compound.

Armour (for armoured cables)
Either corrugated steel tape armour or galvanized steel wire is applied over an inner polyethylene sheath. For steel tape armour, the 0.15mm thick steel tape is coated with a copolymer and applied with an overlap. For steel wire armour, single layer of galvanized steel wire armour is applied

Sheath
LSZH compound HM2 as per VDE 0207-24

Ripcord
Nylon ripcord may be placed parallel to the cores to facilitate sheath removal

Drain Wire
A solid tinned earth/continuity wire shall be laid longitudinally for screened cables
