| Applications : | These cables are fire resistant, flame retardant, low smoke and halogen free, used for emergency instrumentation, communication, control and alarm systems that need to be operational during a 1100℃ hydrocarbon fire. |
| Standards : | IEC 60092-376 IEC 60092-351 IEC 60092-359 IEC 60332-1 IEC 60332-3-22 IEC 60754-1,2 IEC 61034-1,2 NEK 606:2004 IEC 60331-21 |
| Conductors : | Circular tinned annealed stranded copper wire to IEC 60228 class 2. |
| Insulation : | Mica tape + Halogen free EPR compound. |
| Twinning : | Colour coded cores twisted together. |
| Collective Shielding : | Pairs/triples are layed up and collectively screened by copper backed polyester tape in contact with a stranded tinned copper drain wire. Pairs/triples are numbered with numbered tape or by numbers printed directly on the insulated conductors. |
| Bedding : | Halogen free compound. |
| Armour : | Tinned copper wire braid. |
| Outer Sheath1 : | Halogen free thermosetting compound, SHF2. |
| HC-fire protection : | Extruded thermoplastic fire protection compound. |
| Taping : | Lapped glass fibre tape. |
| Outer Sheath2 : | Flame retardant halogen-free thermoplastic compound, type SHF1, coloured grey (blue for intrinsically safe). |
