The Aluminum Electrical Conductor Handbook lists a dc resistance of 0.01558 ohm per 1000 ft (or 0.05112 ohm per km) at 20 degree celcius and a 60 Hz resistance of 0.0956 ohm per mile (or 0.0594 ohm per km) at 50 degree celcius for the all-aluminum Marogold conductor, which has 61 strands and whose size is 564 mm2 or 1113 kcmil. Assuming an increase in resistance at 50 degree celcius, and determine the percentage due to skin effect.
