750 kVA 13.2 kV to 208Y/120 V Oil-Filled Distribution Transformer Overview

The 750 kVA oil-immersed three-phase distribution transformer is designed and manufactured by a professional transformer manufacturer to meet the power needs of commercial facilities, utility networks, and industrial applications. This transformer features a 13.2 kV Delta-connected primary and a 208Y/120 V grounded Wye secondary, ensuring stable voltage output and compatibility with North American and South American power distribution systems.

As an experienced transformer manufacturer, we use high-purity oxygen-free copper windings and premium grain-oriented silicon steel (CRGO) laminations for the core to minimize no-load and load losses, thereby improving energy efficiency and service life. The unit is immersed in high-quality mineral insulating oil, which enhances cooling performance and dielectric strength. The sealed tank design provides excellent moisture and dust resistance, making it suitable for harsh outdoor environments and 60 Hz power grids.

Produced by the industry-leading transformer manufacturer Energy Transformer, all units strictly comply with IEC, ANSI, IEEE, CSA, and GOST international standards. The transformer is equipped with multiple safety features including oil level indicators, temperature gauges, pressure relief devices, and optional rapid pressure rise relays to ensure stable and safe operation. Its compact and robust enclosure makes it ideal for commercial buildings, renewable energy projects, construction sites, and urban power distribution networks.
