NEK606 Water Blocked
Offshore & Marine Cables
Water Blocked S10 IYOI(c) 60 V
Applications
- These cables are flame retardant, low smoke and halogen free, used for indoor telecommunication.
Standards
-
IEC 60092-359 IEC 60332-1 IEC 60332-3-22 IEC 60754-1,2 IEC 61034-1,2 NEK 606:2004 VG 95218 part 29
Construction
-
l??? Conductors: Solid tinned copper, 0.5mm.
l??? Insulation: Halogen-free thermoplastic compound PE.
l??? Twinning: Colour coded cores twisted together. Pairs are cross-stranded to finished cable or 10 pair units. The units are stranded to 20 - 30 - 50 pair cables. 2 pair is stranded as a star quad.
l??? Filler: Water blocking fillers, if required.
l??? Wrapping: Polyester tape.
l??? Collective Shielding: The cable core is screened by copper backed polyester tape in contact with a 0.5mm solid tinned drain wire.
l??? Bedding: Halogen-free thermoplastic compound, type SHF1, coloured grey, PETP wrapping tape will be applied over the bedding, if required.
l??? Armour: Copper wire braid, PETP wrapping tape will be applied over the braiding, if required.
l??? Water Blocking Elements: Water blocking tape and strings for providing longitudinal water tightness.
l??? Inner Sheath: Halogen-free thermoplastic compound, type SHF1, coloured grey.
l??? Outer Sheath: Polyurethane for providing transversal water tightness, PE is optional,but can not meet low smoke standard.
