Pad Mounted Power Tank

Pad mounted transformer is a distribution equipment that combines transformer body, high-voltage load switch, fuse and corresponding auxiliary equipment. It was introduced to China by the United States in the early 1990s. Its main body is a transformer, which has the characteristics of compact structure, full sealing, full insulation, and small volume. It can be directly placed outdoors and is suitable for ring network or terminal power supply. Pad mounted transformer oil tank usually refers to the metal shell or oil tank part of the box type transformer, which is a key equipment used for power distribution in the power system. As the core component of a box type transformer, the design and function of the fuel tank directly affect the insulation, heat dissipation, safety, and compactness of the equipment.

• Sealed oil immersed design: The core components (windings, iron cores, switches, etc.) are immersed in insulating oil, achieving full sealing and insulation without the need for safety fences;
• Compact structure: Approximately one-third the volume of a European box transformer, suitable for areas with limited space;
• High protection level: Adopting anti-corrosion spraying, moisture-proof, and anti small animal design, suitable for harsh outdoor environments;
• Standard Capacity Range: Common capacities range from 75 kVA to 5000 kVA, with some manufacturers reaching up to 10000 kVA;
• Connection method: Usually using Dyn11 wiring group, the neutral point does not drift, and the power supply quality is high.

Application scenarios: Commonly found on the streets of residential areas, parking lots in commercial areas, and green belts in industrial parks in North America. It reduces the high voltage of overhead power lines to low voltage available to residents (such as 120/240V).

Key attachments:

No Load Tap Changer: usually external type, which can adjust the voltage after power failure;

Oil Level/Temperature Gauge: Used to monitor the internal status of the oil tank;

Fusing: It may contain Bayonet type fuses or current limiting fuses inside, used to protect transformers.

In summary, the pad mounted transformer oil tank is a professional enclosure that combines high safety, compact structure, and strong weather resistance. Its design philosophy is to ensure that the power supply equipment can operate reliably in an accessible environment without posing any danger to the public.
