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 | 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. | |
