Advantages of Pad-Mounted Transformer
Safety
A pad-mounted transformer typically features a completely enclosed structure that cannot be opened without authorization to protect and encapsulate the high-voltage equipment. This not only ensures normal operation without any external disturbances, but also prevents electric shock risks to protect pedestrians. If the interior is damaged or failed, the high-strength structure of this transformer also limits the failure within the enclosure, protecting surrounding equipment and pedestrian safety. Even in a harsh environment, the pad-mounted still maintains stable operation through its excellent corrosion resistance and sealing performance.
Flexible Installation
Compared to traditional substations, the pad-mounted transformer does not require additional substation building or fencing. It just needs to be combined with a concrete foundation to achieve the installation process. For some commercial and urban projects that are sensitive for space layout, this type of transformer offers a small footprint to reduce 40%- 70% construction costs for you. The pad-mounted transformer also can be installed close to the load, decreasing the electrical lines loss while also optimizing system efficiency.
High Reliability
The pad-mounted transformer typically features sealed tank structures to reduce harmful effects or pollution caused by environmental factors. It offers high reliability to ensure stable operation for long terms of use. In addition, the insulating oil of this transformer is isolated to air, significantly reducing oxidation risks. Due to its enclosed structure, core components of the pad-mounted transformer can be protected to decrease the fail rate, thereby extending its service life.
