On an overhead transformer, what are the high voltage bushings on the primary side called?

Explanation:
High-voltage bushings are labeled to show which winding end they belong to. The primary (high-voltage) side uses H-designations, while the secondary (low-voltage) side uses X-designations. So the two terminals of the HV winding that go to the outside are H1 and H2. The low-voltage ends are typically X1, X2, X3 in a three-phase unit. A bayonet fuse is a protective device, not a transformer bushing, so it doesn’t describe the transformer’s HV connections.
