Application | The cables are used as basic access for ISDN services in central office wiring and cabling for ISDN basic access installation. |
Standards | ER.f5.058 |
Construction | |
Conductors: | Solid annealed bare copper sized 0.5/0.6mm as per ASTM B-3/IEC 60228 class 1 |
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/LSZH |
Ripcord: | Nylon ripcord may be placed parallel to the cores to facilitate sheath removal |
