Cable Construction
Conductor
Copper, class 5 (flexible). The ground conductor is divided into three conductors; the equivalent cross-section is approximately 50% of the section of the phase conductor. For 4G cables, ground conductor has the same cross-section as the phase conductors.
Insulation
XLPE. Standard identification of insulated conductors: 3x + 3G Grey + Brown + Black + Green/yellow (3 G) from 6 mm² onwards. 4G Grey + Brown + Black + Green/yellow up to 4 mm².
Assembly of Cores
For 3x + 3G cables, the three phase conductors are cabled helically with the three protective conductors distributed in the interstices. For 4G cables, the three phase conductors and protection conductor are cabled helically.
Screen
Overlapping aluminium-polyester tape screen with 100% coverage + tinned copper drain wire.
Outer Sheath
Polyolefin LSZH (Low Smoke Zero Halogen).

Installation Conditions
Being very performant cables there are, however, certain precautions that must be taken into account during installation:
- Always respect the bending radius of the cable. Radius below the minimums indicated can cause damage or breakage in the outer sheath.
- Precautions design of the laying. It is necessary that the laying of the cable is done in a careful way, taking care not to damage the outer sheath in irregular areas, sharp edges, etc.
- Fixings/Fastenings. Adapt fastenings so that the cable adopts a natural position in the laying to avoid stress concentration in the outer sheath. Allow a certain degree of freedom of movement in order to absorb possible movements produced by temperature variations.
Installation Methods: Open Air, Buried, In conduit
