Manufactured to comply with or exceed ANSI, IEEE, NEMA, DOE, RUS, and CSA standards, the product is built to provide reliable performance, enhanced safety, and long-term durability. It is carefully engineered and rigorously tested in accordance with ANSI C57.12.00, C57.12.21, C57.12.25, C57.12.28, and C57.12.90 standards to ensure superior enclosure integrity and dependable operation.
Furthermore, the product is produced within ISO 9001 certified quality management systems, maintaining consistent manufacturing quality and high operational performance.
The unit features a dead-front, tamper-resistant construction designed for both loop and radial feed applications. Its crowned or domed tank cover minimizes water retention, improving durability and dependable performance in outdoor conditions. Manufactured from mild steel or stainless steel, the cabinet and tank are protected with high-quality corrosion-resistant coatings that exceed IEEE standards for extended service life.
For easier transportation and installation, the unit is equipped with recessed lifting provisions and a removable sill. Security and accessibility are enhanced with flip-top or hinged doors fitted with stainless steel hinge pins, captive penta-head or hex-head locking bolts, and padlock provisions. In addition, a laser-engraved aluminum nameplate and NEMA/ANSI compliant safety labels provide clear identification and support safe operation.
The unit is equipped with externally clamped 200 A high-voltage bushing wells, making it ideal for both loop and radial feed applications. It also features externally clamped low-voltage threaded stud or spade-type bushings to ensure secure and reliable electrical connectivity. Integrated parking stands provide safe accommodation for elbow connectors, while tank ground pads and a removable ground strap deliver dependable and effective grounding performance.
The transformer is equipped with an automatic pressure relief device that includes provisions for manual operation, ensuring enhanced safety and ease of use. Its dual-fuse primary protection system, comprising 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 improved operational protection, optional features such as a secondary circuit breaker or MagneX® interrupter system are available. The fuse assemblies also incorporate oil-retention and drip-protection mechanisms to reduce environmental risk and enhance containment safety.
The transformer is filled with new, unused electrical-grade mineral oil or Envirotemp™ FR3™ fluid, an ester-based insulating coolant recognized for its fire-resistant and environmentally friendly characteristics. It is equipped with an oil fill and level top plug, along with a bottom drain plug featuring a sampling device for easy maintenance and fluid inspection. Provisions are included for optional installation of temperature, liquid level, and pressure vacuum gauges as required. Optional under-oil surge arresters and grounding connectors are also available to improve system protection and support reliable operation.
Designed for continuous duty at a 65 °C average winding temperature rise, the transformer is compatible with both 50 Hz and 60 Hz electrical systems. It is engineered for primary voltage ratings up to 34.5 kV and secondary voltages from 120 V to 600 V. Each unit is subjected to comprehensive routine ANSI/IEEE testing, including polarity, ratio, resistance, no-load and load losses, impedance, dielectric, induced and impulse, along with leak testing to verify dependable performance and manufacturing quality. Furthermore, the transformer complies with DOE energy efficiency standards and meets NEMA TR-1 sound level requirements.
