What does the term swaging refer to in substation aluminum bus work?

The term swaging in the context of substation aluminum bus work refers to the process of compressing the aluminum material to achieve a desired shape or to create a tight, secure connection between components. This method is often used in electrical installations to ensure low resistance and reliable electrical connections. By compressing the aluminum bus, swaging helps to create a mechanical bond that enhances conductivity and overall performance in a substation environment, making it a critical aspect of ensuring electrical reliability and efficiency.

Other options, while they may relate to different procedures in maintenance or assembly, do not accurately define swaging. For instance, swabbing with cleaner is related to maintenance, roughing with sandpaper pertains to surface preparation, and applying penotrox involves the use of a specific treatment for electrical connections. None of these processes entail the compression aspect that is central to swaging.
