If schedule 80 aluminum tube is used for a substation bus, the maximum length before vibration dampers are needed is?

In the context of using schedule 80 aluminum tube for a substation bus, the maximum length before vibration dampers are required is indeed 17 feet. This specification is crucial for ensuring the structural integrity and reliability of the bus system, as longer spans may lead to increased vibrations that can cause mechanical stress and potential failure over time.

The 17-foot limit is based on engineering principles that account for the material properties of aluminum as well as the typical operational environment of substations, which can be subject to various dynamic forces. By installing vibration dampers beyond this length, the system can mitigate potential issues arising from oscillations and vibrations, thereby enhancing the longevity and safety of the electrical bus system.

Proper adherence to these specifications is essential for maintaining operational efficiency and safeguarding against mechanical failures that could impact the overall functionality of the substation.
