XRUHAKXS (aluminum) and XRUHKXS (copper) are single-core medium-voltage cables with XLPE insulation, a concentric copper screen, and both longitudinal and radial water sealing. The "n" versions offer enhanced flame retardance. Suitable for installation in buildings, power stations, open air, ground, cable trays, and ducts where mechanical damage is not expected.
 
These cables use Class 2 compacted conductors (EN 60228), semi-conducting XLPE layers, water-swellable tapes, a helically applied copper screen, an aluminum/plastic laminate radial barrier, and a weather-resistant PE sheath (black or red for “n”). Rated 6/10 kV and tested at 21 kV, they operate from –60°C to +50°C, withstand +250°C short-circuit temperatures, and support conductor temperatures up to +90°C. Minimum installation temperature is –20°C, with a bending radius of 15 × D. Sizes range from 25 mm² to 1000 mm² (Al) and 16 mm² to 35 mm² (Cu).
