description

Conductor: Annealed tinned electrolytic copper, 7-wire stranding, class B.
Insulation: XLPE or expanded polyolefin.
Identification:   
Stranding
: Consistent stable twisted pair.
Shield: Aluminium-polyester tape helical wrap plus tinned-copper drain-wire conductor.
Sheath: Orange PVC (blue for intrinsically safe systems); fire-retardant; sunlight and hydrocarbon-resistant.
Stripping: Polyamide ripcord under the sheath.

optionals

Armour: Zinc-plated steel served-wire helical armour or aluminum interlock armour plus orange PVC sheath (blue for intrinsically safe systems); fire-retardant; sunlight and hydrocarbon-resistant. These cables are UL certified for direct earth burial.

See Technical Note # 8, "Wire armour properties"

installation

Assembly: Minimum bend radius is 7xOD (unarmoured versions) and 12xOD (armoured versions).
Maximum pulling tension: 5daN/sq mm on copper conductors. Wire-armoured cables can withstand 10daN/sq mm on the armour wires.
