On an overhead transformer, what are the low voltage secondary bushings called?

Explanation:
Low voltage secondary bushings on a three‑phase transformer are designated with X1, X2, and X3. In transformer labeling, the high‑voltage side uses H (such as H1, H2), while the low‑voltage or secondary side uses X (X1, X2, X3), with each X corresponding to a phase. H1A/H1B would be used for HV taps or parallel/series connections in some designs, not for the LV bushings. A bayonet fuse is a protective device, not a winding terminal. So the LV secondary bushings are X1, X2, and X3.
