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 determination of the maximum length before vibration dampers are required is based on the tube's susceptibility to vibrations, which can be caused by factors such as wind, thermal expansion, and electrical loads.

For schedule 80 aluminum tubing, regulatory and engineering standards typically indicate that lengths exceeding 17 feet would require the installation of vibration dampers to mitigate potential oscillation and ensure system integrity. This standard helps prevent issues such as fatigue or structural failure, which can arise from excessive movement over longer spans. The use of dampers is crucial for enhancing the longevity and reliability of the bus system in high-stress applications commonly found in substations.

Understanding the need for vibration dampers at a length of 17 feet encapsulates the importance of design principles in electrical infrastructure, particularly in handling dynamic forces.
