(N)A2XS(F)2Y · MEDIUM VOLTAGE POWER CABLE

(N)A2XS(F)2Y Aluminium XLPE Medium Voltage Cable

(N)A2XS(F)2Y is a single-core medium-voltage power cable with a Class 2 circular compacted aluminium conductor, XLPE insulation, a copper wire and tape screen, longitudinal water-blocking layers and a black polyethylene (PE) outer sheath.

Designed for fixed medium-voltage power distribution in underground networks, cable ducts, substations, power infrastructure and industrial installations. The swellable water-blocking tapes help limit longitudinal water propagation within the cable.

Technical note Current carrying capacities in ground are based on 20°C soil temperature, 70 cm laying depth, soil thermal resistivity of 1 K·m/W and load factor 0.7. Current carrying capacities in air are based on 30°C ambient temperature and load factor 1.0. Flat formation uses cable spacing of 1 × cable outer diameter in air and 7 cm in ground. Dimensions and weights are approximate.
