Conductor operating temperature : 90ºC

r = Resistive Component

x = Reactive Component

z = Impedance Value

*Spacings larger than one cable diameter will result in a larger voltage drop.

For cables having conductors of 16mm2 or less cross-sectional area their inductances can be ignored and (mV/A/m)r values

only are tabulated. For cables having conductors greater than 16mm2, cross-sectional area the impedance 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.
