2000 kVA 3-Phase Padmount Step-Down Distribution Transformer

Designed for critical power distribution applications, the 2000 kVA 3-Phase Padmount Transformer provides reliable medium-voltage to low-voltage power conversion for commercial, industrial, municipal, and utility infrastructure. Engineered for long-term outdoor service, this transformer combines robust construction, efficient thermal performance, and dependable voltage regulation to support demanding electrical loads where uninterrupted operation is essential.

With a primary voltage rating of 12,470Y/7,200V and a secondary output of 277/480V, the transformer efficiently steps down utility distribution voltage to a utilization-level voltage commonly used for large facilities, manufacturing operations, data centers, water treatment plants, healthcare campuses, educational institutions, and other high-capacity electrical systems. Its 2000 kVA capacity provides substantial power handling capability, making it well-suited for applications requiring continuous operation and support for significant motor, lighting, HVAC, and process loads.

The transformer is housed in a padmount, tamper-resistant steel enclosure designed for secure ground-level installation in outdoor environments. The compact footprint allows placement in commercial developments, industrial campuses, utility distribution networks, and public-access locations while maintaining safety and accessibility for service personnel. The dead-front design enhances operator protection and complies with modern utility and industrial safety practices.

Cooling is achieved through a proven Oil Natural Air Natural (ONAN) system, utilizing natural circulation of insulating mineral oil and ambient air to dissipate heat without the need for pumps, fans, or other mechanically driven cooling equipment. This passive cooling approach improves reliability, reduces maintenance requirements, minimizes operating costs, and contributes to a longer service life by eliminating moving components that can wear over time.

The transformer employs high-quality mineral oil insulation, providing excellent dielectric strength and heat transfer characteristics. The insulating fluid helps maintain winding temperatures within design limits, supports fault withstand capability, and ensures stable performance across varying environmental conditions. Combined with durable core-and-coil construction, the insulation system is engineered to deliver dependable operation under continuous-duty loading and fluctuating demand profiles.

Operating at 60 Hz and configured for three-phase service, this transformer delivers balanced power distribution and efficient energy transfer throughout the electrical system. Its design supports reliable voltage regulation and minimizes losses, helping facility operators maintain power quality while maximizing overall system efficiency.

Built to meet the rigorous demands of modern electrical infrastructure, the 2000 kVA 3-Phase Padmount Transformer serves as a critical link between utility distribution networks and end-user equipment. Whether deployed in industrial facilities, commercial developments, renewable energy projects, or utility distribution systems, it provides the performance, durability, and operational reliability required for mission-critical power applications.
