What is the maximum sag allowed when installing aerial drops or mid spans?

The maximum sag allowed when installing aerial drops or mid spans is crucial for ensuring the safety and reliability of the cable installation. A sag limit of 9 inches helps to maintain an appropriate tension level on the cable while also allowing for proper clearance from objects below, such as ground vehicles or pedestrians. This specific measurement also aids in preventing excessive wear and stress on the cable due to environmental factors like wind and temperature fluctuations, which can cause further sag over time.

A sag greater than 9 inches could lead to issues such as increased risk of the cable touching objects below, improper cable alignment, and potential damage to the infrastructure. This standard is established based on engineering best practices and safety regulations that prioritize the longevity of the cable and the safety of the public.
