1. Conductor: Compact stranded aluminium 1350, class 2.
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.
5. Screen: Copper tapes.
6. Separation sheath: HFFR thermoplastic compound.
7 & 8. Two Layers armour: Aluminium wires.
9. Tape: Polyester.
10. Outer sheath: HFFR thermoplastic compound.
Conductor temperature of 90ºC for normal operation, 130°C for emergency overload and 250°C for short circuit conditions. Its armour provides additional mechanical protection. The separation sheath and outer sheath have the following characteristics: Fire retardant, low emission dense smoke and halogen free. Adequate resistance to oils.
