Determine the resistance at 20 °C and inductive reactance of a seven-strand, all aluminum conductor having a diameter of 50 mil per strand, installed in a single-phase 1 km long distribution line. (The resistivity of Aluminum is 17ohm-cmil per foot at 20 °C). The line is 3 meters apart. Include the effect of spiraling. In a 30-km span, 3-phase line, calculate the per-phase resistance at 50°C, inductive reactance and capacitive reactance of the transmission line that uses triangular bundled conductors. The conductors in the bundle are 397.5 MCM ACSR, 26/7 and are spaced 10 inches per conductor and 10 meters per line. A 50-mile, 60-hz, three-phase line composed of one-900 MCM, 54/7 ACSR conductor per phase has flat horizontal spacing of 30 ft between adjacent conductors. Compare the inductive capacitive reactance with that of a line using a three-conductor bundle of 300 MCM ACSR 26/7 conductors having the same total cross- sectional area as the single-conductor line and 30-ft spacing measured from the center of the bundles. The equilateral spacing between conductors in the bundle is 10 inches. A 60-Hz, double circuit, 30-mile, three-phase line, each vertically spaced 3 meters between adjacent conductors are spaced 10 meters apart. If the conductor is 2-366.4 MCM, 30/7, calculate the following when the line is transposed: 8A3 LEW ME a. The total resistance of the line at 60° C. b. C. The total inductive reactance of the line.
