description

Conductor: Annealed electrolytic copper, 7-wire stranding, class B.
Insulation: Mica tape helical wrap plus extruded LSZH layer.
Identification:

  Standard Intrinsically Safe
- 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: orange LSZH- HFFR (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 aluminium interlock armour plus orange LSZH 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
