Product Description

Application

The cables are designed for digital communications where 120Ω impedance are required during copper interconnection. They are used as primary access for ISDN services inside buildings between network termination equipment and subscriber termination equipment (G703 E1/T1 systems 2.048 or 1.544 Mbps).
Conductors
Solid annealed bare copper sized 0.4/0.5mm as per ASTM B-3/class 1 of IEC 60228
Insulation
Solid polyethylene as per ASTM D 1248/IEC 60708
Twisted Pairs
Insulated conductors are twisted into pairs with varying lays to minimize crosstalk
Cable Core Assembly
The pairs are cabled together in layers of 12, 13 & 25 pair unit to form the cable core. Units are identified by colour coded binders
Core Wrapping
One or more non-hygroscopic polyester tapes are helically or longitudinally laid with an overlap
Screen
Aluminium/Polyester tape is applied longitudinally with an overlap
Sheath
PVC or LSZH compound
Ripcord
Nylon ripcord may be placed parallel to the cores to facilitate sheath removal
Armour (optional)
Corrugated steel tape armour
Additional Outer Sheath
PVC (for NYY Cables); PE (for Armoured Cables); LSZH
Drain Wire
Solid tinned copper 0.5mm drain wire may be laid longitudinally under the screen
