Construction
| 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. |
| Outer Sheath |
Halogen free thermosetting compound, SHF2, coloured grey (blue for intrinsically safe). |
