Indoor Switchboard Telephone Cables to CW 12931
Applications
The cables are designed to handle low frequency signals for short range applications,suitable for cross connecting individual items of switchboard equipment and to connect exchanges with internal distribution points. The cables are intended to be terminated in Insulation/displacement Connectors (IDC).
Standards
- CW 1293
- IEC 60189-2
- IEC 60332-1
- UL1581 VW-1 & UL1666
- IEEE 383CI.IE
Construction
 |
 |
| Conductors | Solid annealed bare copper 0.4/0.5/0.6/0.9mm as per class 1 of BS 6360 and IEC 60228. |
| Insulation | Colour coded PVC T154 to BS 7878 or equivalent. LSZH option can be offered upon request. |
| Twisted Pairs | Insulated conductors are twisted into pairs with varying lay length to minimize crosstalk. |
| Cabling Element | Twisted Pairs/Triples/Quads. |
| 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. For unit construction, the elements shall be pairs and shall be laid up as units or sub-units. Each unit shall consist of 20 pair. |
| Core Wrapping | Cable containing more than 12 wires has a polyester tape applied over the cable core prior to sheathing. |
| Screen (optional) | An aluminium polyester foil shield can be provided for fully enclosing the core with an overlap. |
| Sheath | PVC TM51 to BS 7878 or equivalent. Grey, White or Cream colours are standard. LSZH option can be offered upon request. |
| Ripcord | Nylon ripcord may be placed parallel to the cores to facilitate sheath removal. |
| Drain Wire (optional) | For screened cables, a solid tinned copper drain wire may be longitudinally laid to ensure electrical continuity of the screen. |
