Telephone Cable – Outdoor
Multipair PVC, steel wire armoured
Application
Multi-pair armoured telecommunications cables are intended for use in telecommunications links over relatively short runs in a robust environment that requires added mechanical protection (e.g. Mining environment)

| Conductor: | Plain annealed copper conductors (Tinned annealed copper conductors also available). |
| Insulation: | Polyvinyl Chloride (PVC) insulation. |
| Twinning: | Pair twisting – Two insulated conductors are twisted together to form a pair, identification being effected by colour of the insulation. |
| Cable Core Assembly: | Twisted pairs are stranded into concentric layers starting with pair number 1 in the centre of the cable. |
| Bedding Sheath: | Low halogen Polyvinyl Chloride (LH PVC). |
| Armouring: | Galvanized steel wire armouring (also available in double steel wire armouring with a Bituminize rayon tape in between the two steel wire layers). |
| Sheath: | Low halogen Polyvinyl Chloride (LH PVC). |
Alternative sheath colours are available on request
Available in 500m drums
