Construction
| 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. |
| Individual Shielding |
Each pairs/triples are screened by copper backed polyester tape in contact with a stranded tinned copper drain wire and wrapped with polyester tape. 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). |
