Marine Cable

S12 RU(c) 250 V Marine unarmoured cables are flame retardant, low smoke and halogen free, used for

instrumentation, communication, control and alarm systems.

Standards :

IEC 60092-376

IEC 60092-360

IEC 60332-1

IEC 60332-3-22

IEC 60754-1,2

IEC 61034-1,2

NEK 606

• 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.

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