Water Blocked P2 or P2/P9 RFOU/TFOU 3.6/6KV
Applications
These cables are partially water blocked, flame retardant, low smoke, halogen free and mud resistant, used for fixed installation for medium voltage power.
Standards
-
IEC 60092-353 IEC 60092-351 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: Circular tinned annealed stranded copper to IEC 60228 class 2.
l Conductor Screen: Semi conducting material.
l Insulation: Halogen-free EPR. XLPE can be offered as an option (for TFOU cable).
l Insulation Screen: Semi conducting material and tinned copper wire braid.
l Filler: Water blocking fillers, if required.
l Bedding: Halogen free compound, PETP wrapping tape will be applied over the bedding, if required.
l Armour: Tinned 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 thermosetting compound, SHF2 (for TYPE P2), or halogen free mud resistant thermosetting compound, SHF MUD (for TYPE P2/P9), coloured red.
l Outer Sheath: Polyurethane for providing transversal water tightness, PE is optional,but can not meet low smoke standard.
