Telephone Cable – Outdoor

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
