Transformer Specifications:

The Huapeng 3000kVA Pad Transformer is a robust three-phase transformer with a capacity of 3000 kVA, making it suitable for various industrial and utility applications. Its low impedance of 5.75% ensures efficient power transfer while minimizing energy losses. This transformer operates with a cooling system consisting of KNAN and FR3 oil, guaranteeing effective temperature control. Its Dyn1 vector group configuration provides flexibility in power distribution setups, and it complies with DOE-2016 efficiency standards, reflecting its commitment to energy efficiency. With high voltage rated at 12,470 Delta Volts and a 95 kV BIL, it can handle demanding voltage requirements. The inclusion of multiple taps, both above and below the normal rating, allows for precise voltage adjustments, ensuring optimal performance. Additionally, its load-break switching capability at 15-38kV and 200A provides versatility in managing electrical circuits.

Safety and Accessories:

The Huapeng 3000kVA Pad Transformer prioritizes safety and reliability. It features overcurrent protection using bayonet fuses in series with Partial-Range Current-Limiting fuses, minimizing the risk of electrical faults. With a low voltage rating of 415 Volts and a 30 kV BIL, it provides consistent power distribution on the low-voltage side. The transformer is equipped with IEEE standard two-hole ground pads for grounding, enhancing safety. Its construction includes a durable enclosure with a bolted or welded cover, ensuring the security of internal components. The presence of gauges, including liquid level, thermometer, pressure/vacuum gauge, and a drain valve with a sampler in the low-voltage compartment, offers real-time monitoring and maintenance convenience. Lastly, the Munsell Green topcoat adds a protective layer to the transformer's exterior while adhering to industry standards.
