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)
Steel wire armoured telecommunication

Mutual Capacitance (max. average @ 800Hz) nF/km | 90 | 90 |
Capacity Unbalance p-p (800Hz Ind max.) pF/200m | 195 | 195 |
Insulation Resistance @ 500V DC (individual minimum) MΩ.km | 80 | 80 |
High Voltage kV DC for 1 minute without breakdown | 1 | 1 |
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
