Engineering Data

 

  1. Cross Sectional Area
    Cross Sectional area = π/4xd² mm²    Where d = conductor diameter in mm
  2. Weight of Conductor
    Copper conductor : 6.98218 x (d)²    Where d = conductor dia Based on Density of copper = 8.890 g/cc
  3. Conductor resistance Copper Conductor
    Nominal resistivity annealed conductor, as in enamelled wire, according to IEC 60317-0-1 specification = 1/58.5=0.017094 ohm.mm²/m

For AWG sizes, Resistivity as specified in NEMA MW 1000-2003 = max. 0.017241 (=1/58) ohm.mm²/m, corresponding to conductivity 100%(IACS) is taken as base.
