Features of American box transformer

1. Compact structure, small size, easy installation and flexibility;
2. Fully insulated, fully sealed structure, safe, reliable, maintenance-free, and reliable protection of personal safety;
3. The high-voltage side is protected by double fuses. The plug-in fuse is a double-sensitive fuse (temperature, current), and the backup fuse is a current-limiting fuse, which reduces operating costs;
4. The high-voltage incoming line adopts a cable connector structure, which is fully insulated, safe, reliable and easy to operate;
5. It can be used for both ring network and terminal. The conversion is very convenient and improves the reliability of power supply.
6. The transformer has a three-phase three-column or three-phase five-column structure. The iron core adopts stepped joint technology or rolled core technology. It has low noise, low loss, and strong resistance to short circuit and overload.
7. Using special processes of vacuum drying and vacuum oil injection, our company will extend this process used in 110kV products to 10kV products, providing a strong guarantee for improving product quality.
8. The cabinet can adopt anti-corrosion design and special spray painting treatment according to the requirements of the operating environment. It has the “three prevention” functions, that is, anti-condensation, anti-salt spray, and anti-mold functions, and can meet the anti-corrosion requirements in high temperature and high humidity environments.

Scope of application

①In urban public power distribution systems, when the load increases in residential areas and busy streets, the transformer capacity needs to be increased.

② Temporary power supply at the construction site: If there are existing buildings, it is necessary to modify or add electrical equipment, field operations and power supply for outdoor working places, such as oil fields, mining, ports, terminals, stations, etc.
