Electrical Characteristics
| Conductors | Circular tinned annealed stranded copper wire to IEC 60228 class 2. |
| Insulation | Halogen free EPR compound. |
| Twinning | Colour coded cores twisted together. |
| Individual 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. | |
| Outer Sheath | Halogen free thermosetting compound, SHF2, coloured grey (blue for intrinsically safe). |
