Water Blocked S11 RU(i) 250 V
Applications
These unarmoured cables are partially water blocked, flame retardant, low smoke and halogen-free, and 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 |

Construction
Conductors: Circular tinned annealed stranded copper wire to IEC 60228 class 2.
Insulation: Halogen-free EPR compound.
Twinning: Colour-coded cores twisted together.
Filler: Water blocking fillers, if required.
Individual Shielding: Each pair/triples are screened by copper-backed polyester tape in contact with a stranded tinned copper drain wire and wrapped with polyester tape. Pairs/triples are numbered with numbered tape or by numbers printed directly on the insulated conductors.
Filler: Water blocking fillers, if required.
Water Blocking Elements: Water blocking tape and strings for providing longitudinal
water tightness.
Inner Sheath: Halogen-free thermosetting compound, SHF2, colored grey (blue for intrinsically safe).
Outer Sheath: Polyurethane for providing transversal water tightness, PE is optional,but can not meet low smoke standard.
