description

Conductor: Annealed electrolytic copper, 7-wire strading, class B.
Insulation: PVC.
Identification:

- Pair:        
- Triad:        
- Quad:        

Lay length: 50 mm (20 twists/m).
Unshielded pair: Polyester tape wrap.
Shield: Aluminium-polyester tape helical wrap plus tinned-copper drain-wire conductor, 7-wire stranding, class B.
Sheath: Red PVC, fire-retardant, sunlight-resistant.
Stripping: Polyamide ripcord under the sheath.

optionals

Insulation: High-density polyethylene, UL Listed PLTC.
Armour: Zinc-plated steel served-wire helical armour or aluminium interlock armour plus red PVC sheath; fire-retardant; sunlight-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/mm2 on copper conductors. Wire-armoured cables can withstand 10daN/mm2 on the armour wires.
Assembly temperature: 5ºC or higher.

alternatives

Construction requirements: As per ICEA S 73-532 (300V and 600V), British Standard 5308, EN 50288-7 and NBR 10300.
Materials: These data are relevant to the standard version of this cable. Other solutions can be made to order based on the different materials and construction alternatives described in the technical information appendix.
