The three phase pad mounted distribution transformers provide a reliable and affordable solution for clients who need to reduce their overall operating costs. They are low-profile, compartment-type transformers, which are generally used for step-down purposes from an underground primary cable supply suitable for mounting outdoors on pads without additional protective enclosures, and meet the following standard: IEC60076, ANSI/IEEEC57.12.00, C57.12.20,C57.12.38, C57.12.90, BS171, SABS 780 etc.
