Designed to meet or surpass ANSI, IEEE, NEMA, DOE, RUS, and CSA standards, the product delivers dependable performance, improved safety, and extended service life. It is precisely engineered and thoroughly tested in accordance with ANSI C57.12.00, C57.12.21, C57.12.25, C57.12.28, and C57.12.90 standards to ensure reliable operation and superior enclosure integrity.
Additionally, the product is manufactured under ISO 9001 certified quality management systems to maintain consistent production quality and high-performance standards.
Built with a dead-front, tamper-resistant design, the unit is suitable for both loop and radial feed configurations. The crowned or domed tank cover helps prevent water accumulation, enhancing durability and reliable performance in outdoor environments. Constructed from mild steel or stainless steel, the cabinet and tank are finished with advanced corrosion-resistant coatings that exceed IEEE standards for long-lasting protection.
To simplify handling and installation, the unit incorporates recessed lifting provisions and a removable sill. Enhanced security and accessibility are provided through flip-top or hinged doors equipped with stainless steel hinge pins, captive penta-head or hex-head locking bolts, and padlock provisions. A laser-engraved aluminum nameplate along with NEMA/ANSI compliant safety labels ensures clear identification and promotes safe operation.
The unit is fitted with externally clamped 200 A high-voltage bushing wells, designed to support both loop and radial feed systems. It also includes externally clamped low-voltage threaded stud or spade-type bushings for secure and reliable electrical connections. Integrated parking stands allow safe positioning of elbow connectors, while tank ground pads and a removable ground strap ensure effective and dependable grounding.
The transformer is fitted with an automatic pressure relief device with manual operating capability for added safety and operational convenience. Its dual-fuse primary protection system, consisting of a bay-o-net expulsion fuse paired in series with a current-limiting fuse, ensures reliable fault protection and overload indication in accordance with utility standards.
To enhance operational safety, optional protection solutions such as a secondary circuit breaker or MagneX® interrupter system can also be provided. In addition, the fuse assemblies are designed with oil-retention and drip-protection features to minimize environmental impact and improve overall containment safety.
Engineered for continuous operation at a 65 °C average winding temperature rise, the transformer is suitable for both 50 Hz and 60 Hz power systems. It supports primary voltage ratings up to 34.5 kV and secondary voltages ranging from 120 V to 600 V. Every unit undergoes extensive routine ANSI/IEEE testing, including polarity, ratio, resistance, no-load and load losses, impedance, dielectric, induced and impulse, as well as leak tests to ensure reliable performance and superior manufacturing quality. In addition, the transformer meets DOE energy efficiency regulations and complies with NEMA TR-1 audible sound level standards.
