Pad Mounted Transformers

Cable box / Bus duct

Pad mounted transformers are used in a variety of applications. These units are generally equipped with cable boxes on opposite ends for terminating the cables. The position of the cable boxes is determined based on the rating of the transformers and end user's requirements.

The transformers are offered in hermetically sealed construction and the tank is made up of corrugated fins. Units with detachable radiators can also be offered. The windings are generally made of copper, however, aluminum windings can also be offered. The standard transformer complies with all relevant standards including IEC / SASO.
