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).
