What is the primary risk of having a conductor sag too tightly?

The primary risk associated with having a conductor sag too tightly is safety hazards and potential failure. When a conductor is under excessive tension, it can lead to a variety of issues, including physical fatigue in the material, which can ultimately result in the conductor breaking or failing. This not only poses a danger to the integrity of the electrical system but also creates significant safety risks for individuals who may be in the vicinity, as well as for any infrastructure that the conductor may come into contact with in the event of failure.

Additionally, tight sag can stress the supporting structures and hardware, which might not be designed to support such loads for extended periods. This aspect further highlights the importance of maintaining appropriate sag levels to ensure both the reliability of the electrical system and the safety of the surrounding environment.
