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.
