NEK606 Instrumentation Cables S2 or S2/S6 RFOU(c) 250V

NEK606 Instrumentation Cables S2 or S2/S6 RFOU(c) 250V

Applications

S2 or S2/S6 RFOU(i) 250V Marine Cable s are flame retardant, low smoke, halogen free and mud resistant, used for instrumentation, communication,control and alarm systems.

Standards

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).
