![]() THe NESC heavy loading conditions are 13mm radial ice, 0.19 kPa transverse wind, and a constant of 4.3782 N/m. THe limiting condition, as determined by the Bureau, for this conductor under NESC heavy loading conditions is 33-1/3 percent of the ultimate strength at minus 40 ☌ initial, no load. "For example, if we string a 242 mm 2, ACSR, 24/7 conductor on aĒ13.4-m ruling span, the initial sag at minus 18 ☌ with no ice and no wind will be 2,549mm, and the tension will be 19,700N. of Interior, Water and Power Resources Services US Government Print. ![]() ![]() Transmissions line design manual: a guide for the investigation, development, and design of power transmission lines.
