What is a Three Phase Pad Mounted Transformer
A Three Phase Pad Mounted Transformer is used to efficiently convert high voltage power for distribution in commercial, industrial, and residential applications. Mounted on a concrete pad, it features a weather-resistant enclosure, making it suitable for both urban and remote outdoor installations. This transformer is designed to handle three-phase power, reducing high transmission voltages to lower, usable voltages for end-users. It is built to operate reliably in various environmental conditions, offering a secure and durable power solution.
Common specifications include power ratings from 150 kVA to 4500 kVA, primary voltages of 12,470V or 35,000V, and secondary voltages of 480V or 600V. These transformers utilize oil-immersed cooling systems, achieving up to 99.15% efficiency with minimal maintenance requirements. With UL, cUL, CSA, SGS, and GOST certifications, they meet international safety and quality standards, ensuring long-term, reliable performance for critical infrastructure.

Three phase Pad Mounted Transformer Sizes vary based on the power rating, voltage specifications, and application requirements. Common sizes for pad mounted transformers range from 75 kVA to 4500 kVA, though larger units can be customized for more substantial power needs. For instance, a 750 kVA transformer typically has dimensions around 60 inches in width, 72 inches in depth, and 90 inches in height, making it suitable for medium to large industrial or commercial applications. These transformers are designed to be compact yet robust, ensuring reliable power distribution while occupying minimal ground space.
The size of a pad mounted transformer also depends on factors like primary voltage, secondary voltage, and cooling requirements. Smaller units (up to 150 kVA) are generally more compact and are often used in residential or light commercial settings. In contrast, larger units, such as the 500 kVA and 750 kVA models, are equipped with advanced cooling systems and tap changers to ensure stable performance under high loads. These larger transformers require more substantial enclosures to house the necessary components but are ideal for heavy-duty industrial operations or expansive power distribution networks.

750 kVA Three Phase Pad Mounted Transformer Types
750 kVA Three Phase Pad Mounted Transformers are available in two configurations: Loop Feed and Radial Feed, both designed to meet U.S. Department of Energy (DOE) efficiency standards.
- Loop Feed transformers are perfect for applications requiring redundancy and high reliability. In this setup, the transformer connects to a looped network, ensuring continuous power even if part of the system fails. This configuration is ideal for urban areas and critical infrastructure where uninterrupted power is crucial.
- Radial Feed transformers are used in systems where power is supplied from a single central point. They offer a cost-effective solution for suburban or rural areas where outages are less common.
Both configurations feature durable, weather-resistant enclosures and efficient components like copper windings and oil-immersed cooling systems, ensuring minimal heat buildup, low losses, and long-term reliability in various environmental conditions.
