Sph 35 mm 2. Systems - Part 2. In general the cable impedance can be calculated in accordance with IEC 60909-2 Short-circuit currents in three-phase ac. For situations not covered by IEC 60909 we can use the fundamental. This standard give gives appropriate formulae for a variety of single and multi-core cables with or without metallic sheaths or shields. The final step is to select the minimum size of cable in the previous steps.
Cable Sizing Calculations You can not work out R1 R2 with the resistivity of copper cable I linked to up to 600mm if you had the length of the cable.
