NA2XSERY is a medium-voltage (MV), 3-core armored power cable constructed as follows:
Aluminium conductor (Class 2, stranded)
XLPE (cross-linked polyethylene) insulation
Copper tape screen over each insulated core
Galvanized steel wire armor (GSWA) for mechanical protection
PVC outer sheath
This configuration ensures electrical reliability, mechanical robustness, and electromagnetic shielding.
MV power distribution in industrial plants, substations, utility grids
Suitable for underground and outdoor installations
Areas requiring high mechanical protection and moderate electromagnetic shielding
Direct burial in ground (suitable for rocky or rough soil)
In ducts or cable trays
Harsh or corrosive environments (with appropriate sheath formulation)
Resistant to UV radiation (black PVC)
Withstands moisture, chemical exposure, and mechanical stress
