The 225 KVA transformer and 252 KVA transformer from Evernew-Transformator, one of the top transformer manufacturers in China, are engineered to deliver reliable, efficient, and safe power distribution. These pad mounted liquid-immersed transformers are specifically designed for various applications, including outdoor environments, utilities, and industrial operations, ensuring stable voltage supply, reduced operational costs, and extended service life. The 225 KVA transformer meets multiple international standards to accommodate diverse installation environments.
Capacity and Temperature Rise
The 225 KVA transformer has a rated power of 225 KVA (55°C rise) and 252 KVA (65°C rise), ensuring high efficiency under load and minimizing thermal losses. The lower temperature rise contributes to the longevity of the 225 KVA transformer and enhances performance under heavy load conditions. It is ideal for environments requiring prolonged high-capacity operation.
Efficient Cooling System
This transformer utilizes a KNAN (Kerosene/Natural Air/Natural Convection) cooling system that includes 126 gallons of biodegradable cooling fluid, such as FR3 fluid. Compared to conventional mineral oil, FR3 fluid exhibits excellent thermal performance, allowing the 225 KVA transformer to handle loads of up to 120% capacity while ensuring safety and environmental compliance. Its non-toxic nature makes it an eco-friendly choice for sustainable energy systems.
Electrical Configuration and Operation
- Primäre Spannung: 13200V, Three-phase Delta
- Sekundäre Spannung: 480Y/277, Three-phase Wye-N configuration
- Impedance Range: 1.2% – 6.0%, with typical impedance values between 3.10% and 5.75%
- Load Tap Changer (LTC): Equipped with a four-position load tap changer that allows for seamless transition between A phase, B phase, or a combination of A + B phase bus, providing flexibility and minimizing disruptions during operation.
Advanced Safety Features
Safety is a top priority for Evernew Transformer. This 225 KVA transformer incorporates multiple safety mechanisms, including:
- Arc Suppression Devices: Prevents overvoltage and surges.
- High Voltage Fuses: Including partial-range current-limiting fuses to protect against overloads or short circuits.
- Automatic Pressure Release Valve (PRV): Releases built-up pressure after activation to prevent internal damage.
