Box-type transformers integrate traditional transformers into a box-shaped casing, featuring small size, light weight, low noise, low loss, and high reliability. They are widely used in residential communities, commercial centers, power stations, airports, factories, mines, enterprises, hospitals, schools, and other locations.
Combined transformers are particularly suitable for load centers of urban power grids, residential areas, hospitals, schools, airports, and railway stations to reduce losses and improve power quality. In the industrial sector, combined transformers are widely used in various factories, mines, ports, and petrochemical enterprises. In the new energy field, they are suitable for locations with harsh natural conditions, such as wind farms (beachsides, deserts) and photovoltaic power stations, and dedicated "wind power combined box-type transformers" or "photovoltaic dedicated combined box-type transformers" have been developed. Furthermore, combined transformers are also used for temporary power supply locations such as mobile construction sites. Underground combined transformers can be directly installed in pits, without occupying surface space, making them suitable for urban areas with limited land resources and of significant value in urban power grid renovation and construction.
