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 |
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 Sheath |
Halogen free thermosetting compound, SHF2 (for TYPE S2). |
|
Halogen free MUD resistant thermosetting compound, SHF MUD (for TYPE S2/S6), coloured grey (blue for intrinsically safe). |
