A padmount transformer is mounted on the ground as opposed to a pole mount transformer. Padmount transformer designs are used in electrical power distribution systems to step down voltage from the high voltage terminal of an underground electrical distribution systems to the low voltage terminal thereof going to the end user's electrical system, etc. A typical padmount transformer enclosure includes a tank for holding the core/coil assembly of the padmount transformer immersed in oil or the like, and a wiring cabinet having high and low voltage wiring compartments for enclosing the high and low voltage bushings, respectively, of the transformer, etc. In order to prevent unauthorized access to the core/coil assembly of the padmount transformer held within the tank of the padmount transformer enclosure, the most common prior art practice is to weld a cover over the top of the tank.

Other prior art tank covers are secured with carriage bolt-nut assemblies, and include some means for shield the nuts, etc. Such shielding means result in a cover that protrudes past the top of the tank cover by several inches and causes water, etc., to be trapped along the edge of the cover. The wiring cabinet of a typical prior art padmount transformer enclosure includes left and right sidewalls, and left and right lockable doors that swing open, exposing the high and low voltage wiring compartment. One of the doors swings out to the right and the other door swings out to the left, leaving the front completely open, but the right and left sidewalls remain fixed in place.

It is recommended that a padmount transformer be located in accordance with certain guidelines with respect to exterior building walls. These guidelines are based on insurance industry recommended practices for the location of a padmount transformer outdoors. The building owner and/or tenants fire insurance carrier or local inspection authority may restrict the proximity of the equipment to any part of a building structure. It is the Customer’s responsibility to determine the acceptability of the proposed location to those authorities outside of the Company.
