  • Sunlight resistance, according to ICEA S-93-639 standard.
  • Cable designed to be permanently submerged in water according to the condition AD8, according to the test procedure of the NBR 14039 standard.

Construction

1. Conductor: Compacted Aluminum, class B with moisture blocking.

2. Internal semi-conductor: Extruded compound.

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

4. External semi-conductor: Peelable extruded compound.

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

5. Concentric Neutral: Made up of copper wires N=16mm2, with water blocking tapes before and after the wires.

6. Outer jacket: LDPE compound resistant to heat, abrasion and humidity, resistant to solar rays (SR), black color.
