Water Blocked
P19 or P19/P21 RFOU 12/20KV
Applications
P19 or P19/P21 RFOU 12/20KV 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 P19), or halogen free mud resistant
-
thermosetting compound, SHF MUD (for TYPE P19/P21), coloured red.
-
Outer Sheath: Polyurethane for providing transversal water tightness, PE is optional,but can not meet low
-
smoke standard.
Optional
P20 or P20/P22 RFOU/TFOU 18/30(36) kV.
