S2 or S2/S6 RFOU(i) 250V

Applications

• These cables are flame retardant, low smoke, halogen free and mud resistant, used for instrumentation, communication, control and alarm systems.

Standards

• IEC 60092-376	IEC 60092-351
  IEC 60092-359	IEC 60332-1
  IEC 60332-3-22	IEC 60754-1,2
  IEC 61034-1,2	NEK 606:2004

 

Construction

• Conductors : Circular tinned annealed stranded copper wire to IEC 60228 class 2.
• Insulation : Halogen free EPR compound.
• Twinning : Colour coded cores twisted together.
• Collective 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).
