Electrical Characteristics
| Conductors | Circular tinned 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). |
