Underground Cable 12/20(24) KV Cu/XLPE/SWA/PVC Armoured 3 Core Power Cable 3x95mm2 3x120mm2 3x150mm2

Construction OF Cu/XLPE/SWA/PVC Armoured 3 Core Power Cable :

Conductor:
Plain circular compacted copper or aluminium conductor, according to IEC 60228.

Conductor Screen:
Extruded semi-conductive compound.

Insulation:
Extruded XLPE rated  cross-linked dry curing (triple cross head).

Insulation Screen:
Non-metallic part: Extruded semi-conductive compound.Colour narrow tape for each core under metallic screen for identification.

Metallic Screen:
Copper tape and /or copper wires for each core to achieve screen area  to withstand short circuit current.

Assembly;
The three cores are assembled together with non-hygroscopic  polypropylene yarns  as fillers to form compacted circular.

Inner covering:
Extruded PVC as bedding under armour.

Armour:
Round galvanized steel wires armour (SWA) applied helically over the PVC bedding.

Outer Sheath:
Black or red protective jacket  PVC or PE  corrosion and sunlight resistant. The cables are designed and tested according to IEC specification  standard IEC  60228, 60502-2 and 60811.
