NA2XSYBY (aluminum) and N2XSYBY (copper) are 3-core medium-voltage cables designed for power distribution in environments with higher risk of mechanical damage. Suitable for laying in buildings, power stations, open air, ground, cable trays, and ducts. These cables feature Class 2 stranded, compacted conductors (EN 60228), XLPE insulation with semi-conducting screens, pre-assembled cores, semiconducting filler and tape, copper wire and tape screen, PVC inner covering, galvanized steel tape armor, and a red PVC sheath.
 
Rated 6/10 kV and tested at 21 kV, they operate from –50°C to +50°C and handle short-circuit conditions up to +250°C. Designed for 50 Hz systems, they support a max conductor temperature of +90°C and can be installed from –5°C with a bending radius of 15 × D. Available in sizes from 50 mm² to 300 mm² (Al) and 25 mm² to 25 mm² (Cu).
