NA2XS2Y(2OL) 7.6/13.2 kV 50 mm2 PHC25

Application

Power distribution in medium voltage. As transformer feeders in substations. In power plants, industrial and operation installations, in residential areas and mining installations, in dry or wet locations.

CONSTRUCTION

1. Conductor: Compact stranded aluminium 1350, class 2 (longitudinally watertight inside the conductor).

2. Inner semi-conductor: Extruded.

3. Insulation: Cross linked polyethylene XLPE-TR (Tree retardant).

4. External semi-conductor: Extruded strippable.

These last three components extruded CV (continuous vulcanization) triple extrusion in dry cure process.

5. Screen: Copper wires (longitudinally watertight under and over the screen).

6. Outer sheath: Linear low-density polyethylene LLDPE-UV.

MAIN CHARACTERISTICS

Excellent properties against heat aging. Longitudinally watertight inside the conductor; and under and over screen. The outer sheath has the following characteristics: resistance to abrasion, moisture and sunlight. Adequate resistance to greases and oils. Low emission dense smoke and halogen free.

GAUGE

400 mm2.
