American box

The modular American-style prefabricated substation houses the transformer body, high-voltage load switch, fuses, and other components all within the transformer tank. Because they are immersed in oil, the component size is significantly reduced, resulting in a more compact structure and convenient, flexible installation. It features a fully insulated, fully sealed structure, ensuring safety, reliability, ease of operation, and maintenance-free operation. It is widely used in residential communities, industrial centers, factories, mines, airports, train stations, schools, and other locations.

1. Compact structure, small size, easy and flexible installation;

2. Fully insulated, fully sealed structure, safe, reliable, maintenance-free, and reliably protects personal safety;

3. High-voltage side uses dual fuse protection, with the plug-in fuse having dual-sensitive fuse wires (temperature and current), and the backup fuse being a current-limiting fuse, reducing operating costs;

4. High-voltage incoming line adopts cable connector structure, fully insulated, safe, reliable, and easy to operate;

5. Can be used in both ring networks and terminals, with very convenient switching, improving power supply reliability;

6. Employs special processes of vacuum drying and vacuum oil injection;

7. The enclosure can be designed with corrosion resistance and specially painted according to the requirements of the operating environment, possessing "three-proof" functions, namely anti-condensation, anti-salt spray, and anti-mildew functions, and meeting the corrosion resistance requirements in high-temperature and high-humidity environments.
