How many primary bushings does a conventional transformer have?

Bushings are insulated paths that carry winding connections through the transformer tank. A conventional transformer has one winding for the primary and one for the secondary, and each winding needs its own bushing to connect to the outside circuit while keeping the winding insulated. So, on a standard two-winding transformer, there are two bushings in total—one for the primary and one for the secondary. This is why the typical answer is two. (Three or four bushings would indicate a more complex, multi-winding or multi-phase setup than the standard conventional transformer.)
