Key Advantages of Three-Phase American-Style Pad-Type Transformers
  1. Compact Structure, High Integration, and Space-Saving:
    • "One-Pack Design": High-voltage load switches, backup fuses, plug-in fuses, the transformer, and the low-voltage distribution system are all integrated into a single, sealed oil tank.
    • Small Footprint: Significantly smaller than traditional civil substations or European-style box-type transformers, ideal for land-constrained areas.
    • Aesthetic Appearance: Typically resembling a large green mailbox, blending seamlessly into surroundings.
  2. Fully Sealed, Fully Insulated, and Safe and Reliable:
    • High Protection Rating (IP67 and above): All live parts are immersed in insulating oil, preventing short circuits and ground faults.
    • Maintenance-Free: Fully sealed structure virtually eliminates external maintenance.
    • Operational Safety: External parts accessible to personnel are insulated.
  3. Highly Reliable Power Supply:
    • Powerful Protection Functions: Plug-in fuses protect against transformer faults, backup fuses isolate short-circuit faults.
    • Load switch enables on-load opening and closing.
    • Ring network power supply capability with high-voltage side typically utilizing two-port or four-port design.
  4. Economical and Low Overall Cost:
    • Low Initial Investment: Lower procurement and installation costs compared to building a distribution room.
    • Easy Installation: Comes complete when shipped from the factory.
    • Low Operation and Maintenance Costs: Maintenance-free nature saves significant costs.
  5. Flexibility and Scalability:
    • Plug-and-Play: Can be used as a mobile substation for temporary power needs.
    • Flexible Solutions: Low-voltage side can be flexibly configured according to user needs.
  6. Energy Saving and Environmental Protection:
    • Low Loss: Utilizing high-quality silicon steel sheets and advanced manufacturing processes.
    • Low Noise: Damping effect of the oil tank and oil effectively suppresses vibration.
    • Excellent Oil-Immersed Heat Dissipation: Ensures transformer's overload capacity and service life.
