Engineered to comply with or surpass ANSI, IEEE, NEMA, DOE, RUS, and CSA standards, the product offers dependable performance, improved safety, and extended service life. It is meticulously designed 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 exceptional enclosure integrity.
Additionally, the product is manufactured under ISO 9001 certified quality management systems, maintaining 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 reduce water accumulation, enhancing durability and reliable performance in outdoor environments. Constructed from mild steel or stainless steel, the cabinet and tank are coated with advanced corrosion-resistant finishes that exceed IEEE standards for long-term protection.
To simplify transportation 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 product identification and promotes safe operation.
The unit is equipped with externally clamped 200 A high-voltage bushing wells, making it suitable for both loop and radial feed applications. It also features externally clamped low-voltage threaded stud or spade-type bushings to provide secure and reliable electrical connectivity. Integrated parking stands offer safe accommodation for elbow connectors, while tank ground pads and a removable ground strap ensure reliable and effective grounding performance.
The transformer is equipped with an automatic pressure relief device that includes manual operating provisions for improved safety and ease of operation. Its dual-fuse primary protection system, featuring a bay-o-net expulsion fuse connected in series with a current-limiting fuse, provides dependable fault protection and overload indication in compliance with utility standards.
For enhanced operational protection, optional features such as a secondary circuit breaker or MagneX® interrupter system are available. Additionally, the fuse assemblies incorporate oil-retention and drip-protection mechanisms to reduce environmental risk and strengthen overall containment safety.
The transformer is filled with new, unused electrical-grade mineral oil or Envirotemp™ FR3™ fluid, an ester-based dielectric coolant known for its fire-resistant and eco-friendly properties. It includes an oil fill and level top plug together with a bottom drain plug equipped with a sampling device for convenient maintenance and fluid monitoring. Provisions are available for the optional installation of temperature, liquid level, and pressure vacuum gauges as needed. In addition, optional under-oil surge arresters and grounding connectors can be provided to enhance system protection and ensure dependable operation.
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 accommodates primary voltage ratings up to 34.5 kV and secondary voltages ranging from 120 V to 600 V. Every unit is subjected to 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 standards and complies with NEMA TR-1 audible sound level requirements.
