Single Phase Pad Mounted Transformer For USA Utility

Introducing a utility transformer project tailored for the USA, located in Virginia. This utility initiative requires 215 units of single-phase pad-mounted transformers, all UL listed, including 175 units of 25 kVA and 40 units of 50 kVA.

The end user's project timeline is 90 days. Adherence to IEEE standards is imperative for single-phase transformers. Additionally, the design of transformer components and markings must be customized to meet project specifications.
