1. With the transformer as the core component, it integrates high-voltage control and protection components such as high-voltage load switches and fuses into the transformer tank, creating a compact structure.

2. The Pad Mount Transformer is even smaller in size, with a volume that is roughly equivalent to a conventional oil-immersed transformer of the same capacity, occupying only about one-third of the volume of a European-style box transformer of the same capacity.

3. There are no heat dissipation issues, making the Pad Mount Transformer more capable of handling overload operations.

4. Simplified configuration of high and low-voltage units results in lower manufacturing costs for Pad Mount Transformers.

5. If the Pad Mount Transformer is equipped with our group’s high-flash-point transformer, it becomes even more suitable for high-temperature regions in the summer.

6. Using a sealed tank design, the Pad Mount Transformer eliminates the need for an oil conservator, reducing the routine maintenance workload for the transformer.

Pad Mount Transformer Features:

1. The transformer is oil-immersed.

2. The product is divided into three parts: the transformer body, the high-voltage chamber, and the low-voltage chamber.

3. Using a full-range protective fuse, The high-voltage side employs a terminal-type oil-immersed load switch with a protective fuse.

4. Structural configurations include “T” shape and “L” shape, as well as “H” shape.

5. Load switches and fuses are installed inside the transformer oil tank, utilizing the transformer’s insulating fluid as both insulating and cooling medium, resulting in a compact overall structure with excellent heat dissipation performance.

6. High-voltage side incoming connections utilize high-voltage bushings to facilitate external cable connections.

7. Conventional products have direct outgoing connections on the low-voltage side, with low-voltage solutions customized according to user requirements.

8. The enclosure is constructed from welded steel plates and undergoes anti-corrosion treatment, ensuring an aesthetically pleasing appearance.

9. The high-voltage chamber contains operable components such as load switches, transformer tap changers, and protective fuses. The enclosure is equipped with oil temperature gauges, oil level indicators, pressure relief valves, drain valves, oil sampling valves, outgoing terminals, and, as per user specifications, low-voltage systems, and automated monitoring systems.
