Note: For cables having conductors of 16 mm2 or less cross-sectional area, their inductance can be ignored and (mV/A/m)r, values only are tabulated. For cables having conductor greater than 16 mm2 cross-sectional area the impendence values are given as (mV/A/m)z, together with the resistive component (mV/A/m)r, and the reactive component (mV/A/m)x
