| Application | The cables are designed to handle low frequency signals for short range applications, suitable for internal connection of telephone systems and other communications equipment. Also, they are designed to be terminated in insulation displacement connectors (IDC).Insulated and sheathed in PVC or LSZH, these cables offer an extremely cost effective general signal cable for fixed installation. |
| Standards | CW 1308 |
| Construction | |
| Conductors | Solid annealed copper sized 0.4/0.5mm as per class 1 of BS 6360/IEC 60228 |
| Insulation | Colour coded PVC TI 54/LSZH for copper conductor & PVC TI 54/LSZH for the 1.38mm earth conductor |
| Twisted Pairs | Insulated conductors are twisted into pairs with varying lay length to minimize crosstalk |
| Cabling Element | Pairs or triples |
| Cable Core Assembly | There are two modes of construction: layer construction and unit construction. For layer construction, cables are laid up in concentric layers to form a compact and circular cable. Layer construction is for general use, including two cables for installation in customer’s premises where a good appearance is required. For Unit construction, the elements shall be pairs and laid up as units or sub-units. This include unit of 20 pairs which contain an insulated earth conductor of 1.38mm, for use with customer distribution schemes; unit of 16 pairs for use with the binary number system and unit of 30 pairs for use with Pulse Code Modulation (PCM) systems. |
| Core Wrapping | Cable containing more than 6 pairs have a polyester tape applied over the cable core prior to sheathing |
| Screen (optional) | A 24μ aluminium polyester foil shield can be provided for fully enclosing the core with an overlap |
| Sheath | PVC TM51 grade or LSZH compound. Grey, White, Cream or Black colours are standard |
| Ripcord | Nylon ripcord may be placed parallel to the cores to facilitate sheath removal |
| Drain Wire (optional) | For screened cables, a solid tinned 0.5mm copper drain wire may be longitudinally laid to ensure electrical continuity of the screen |
