Slab type transformers aren't particularly difficult to locate outdoors or
indoors.

An armor channel covers the HV side conductors downward along the side of
the utility pole, as underground service is typical with pad xfmrs.

Various sizes of outdoor-duty types can be seen around commercial sites, and
also mobile home parks and campgrounds.

In a wire mill environment where I worked years ago, the KV lines were run
underground into the facility, and the switchgear, xfmrs and various
cabinets were mounted on a reinforced overhead slab standing on beams.
The 3-phase 460VAC circuits were branched out with buss systems.

Pad mount are more involved than hanging one on the pole. Security and
limiting the access involve a secure fencing system or vault or some other
secure enclosure. Someone will try to steal the copper and run up the
electric demand.
