Determine the dc resistance in ohms per km of Bluebell at 20°C by Eq. (4.2) and the information in Prob. 4.1, and check the result against the value listed in tables of 0.01678 f/ per 1000 ft. Compute the dc resistance in ohms per kilometer at 50°C and compare the result with the ac 60-Hz resistance of 0.1024 flimi listed in tables for this conductor at 50°C. Explain any difference in values. Assume that the increase in resistance due to spiraling is 2%. Prob The all-aluminum conductor (AAC) identified by the code word Bluebell is composed of 37 strands, each having a diameter of 0.1672 in. Tables of character is of AACs list an area of 1,033,500 cmil for this conductor (1 cmil a (w/4) x 10-6 in2). Are these values consistent with each other? Find the overall area of the strands in square millimeters.
