Pad-Mount Transformers for Utility
Pad-Mount Transformers for Utility
Pad-mounted transformers are distribution transformers ground-mounted on a concrete pad that service underground power networks. These unites step down the distribution voltage to the secondary voltage for residential, commercials, and industrial loads. Because they are fully enclosed, quiet, weatherproof, and tamperproof, padmounts are the preferred choice for installation in public areas. Our pad-mounted transformers are available in single-phase, three-phase, and grounding (zig-zag) configurations.
Primary drivers for growth for pad-mount transformers in the utility market include:
- Expansion of rural and urban residential communities.
- Growing investment in upgrade of aging utility infrastructure and transmission & distribution networks.
- Need for safe, low sound, compact, reliable distribution transformers in public access areas.
- High efficiency, DOE guidelines.
- Growth in digital infrastructure with harmonic loading.
Virginia Transformer is a market leader in power transformer manufacturing since 1971. Our leadership in design and manufacturing experience for pad-mount transformer applications for public power and municipal utilities includes special considerations for:
- Operating in harsh outdoor environments.
- Tamperproof design with kirk-key interlock and padlock provisions for public safety.
- Live- or dead-front construction; loop feed or radial feed.
- Designed to meet system harmonic profile.
- Overvoltage and overcurrent protection.
- Saturation and power factor.
Virginia Transformer is the largest U.S.-owned transformer manufacturer in North America. Our custom-engineered units are designed with a 60-year lifespan and delivered with the shortest lead times in the industry.
