The three-phase pad-mounted transformer is an electrical device that converts high voltage to low voltage (or vice versa). It consists of three independent but interconnected single-phase transformers, with each transformer connected to a phase line.

• Primary Voltage Ratings: 34.5-19.92/13.8-7.957/13.2-7.62/12.47-7.2,44 kV or others
• Secondary Voltage Ratings: 240/480/480Y-277/600Y-347 or others
• H.V. TAP RANGE: ±2×2.5% or others
• CONNECTION TYPE: Dyn11/Yyn0 or others
• TYPE: Loop feed/Radial feed
• BIL: 30-200 kV
• Standards: IEEE/ANSI, CSA, IEC, DOE, NEMA
• Application: BESS, EV Charging, Ultiliy, Bitcoin Mining, Data Center，Real Estate, Solar photovoltaic power generation
• Power Rating: 75 kVA—10000 kVA

The key advantages of a three-phase pad-mounted transformer are as follows:

1. Efficiency: Its three-phase structure allows for the transmission of larger power within a smaller space, improving energy efficiency.
2. Stability: The three-phase operation reduces voltage fluctuations and power wastage.
3. Reliability: With multiple separate transformers, if one transformer fails, the others can continue to operate, enhancing system reliability.
4. Cost-effectiveness: Compared to single-phase transformers, three-phase pad-mounted transformers are more cost-effective and efficient in transmission and distribution systems.
