Final answer:
The max length of a sag section is contingent upon specific utility standards and local regulations; therefore, without more context, it is not possible to provide a definitive answer.
Step-by-step explanation:
The question asks about the maximum length of a sag section in the context of utility or power lines where sag refers to the dip of the cable due to its own weight and the impact of various forces such as tension and gravity. The lengths of these sag sections are usually constrained by several factors, including dead ends, angle structures, and the terrain. Without specific engineering standards or utility regulations being referenced, it is challenging to provide a definitive answer as this can vary depending on the design criteria used by different utility companies or prescribed by local regulations.
