Water Blocked P3 or P3/P10 RFOU/TFOU 6/10KV
Applications
These cables are partially water blocked, flame retardant, low smoke, halogen-free and mud resistant, used for fixed installation for medium voltage power.

Construction
Conductors: Circular tinned annealed stranded copper to IEC 60228 class 2.
Conductor Screen: Semi conducting material.
Insulation: Halogen-free EPR. XLPE can be offered as an option (for TFOU cable).
Insulation Screen: Semi conducting material and tinned copper wire braid.
Filler: Water blocking fillers, if required.
Bedding: Halogen free compound, PETP wrapping tape will be applied over the bedding, if required.
Armour: Tinned copper wire braid, PETP wrapping tape will be applied over the
braiding, if required.
Water Blocking Elements: Water blocking tape and strings for providing longitudinal
water tightness.
Inner Sheath: Halogen free thermosetting compound, SHF2 (for TYPE P3), or halogen free mud resistant thermosetting compound, SHF MUD (for TYPE P3/P10), coloured red.
Outer Sheath: Polyurethane for providing transversal water tightness, PE is optional,but can not meet low smoke standard.
