Shield: Aluminium-polyester tape plus tinned-copper braid in SB 1700 and SB 1800 series. Aluminium-polyester tape plus tinned-copper drain wire in SB 2700 series.
Sheath: Grey PVC; fire-retardant; sunlight and hydrocarbon-resistant.
Stripping: Polyamide ripcord under the sheath.
optionals
Armour: Zinc-plated steel served-wire helical armour or aluminium interlock armour plus grey PVC sheath, fire-retardant, sunlight and hydrocarbon-resistant.
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.
Assembly temperature: 5ºC or higher.
