Description
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 1350 aluminium, 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 in dry cure process.
5. Screen: Copper wires (with longitudinally watertihgt under and over the screen).
6. Outer sheath: LLDPE-UV linear low density polyethylene; with anti-rodent compound
Main characteristics
