The photovoltaic grid-connected box is a photovoltaic power station built near the user's site. Its operation mode is self-generation and self-consumption on the user side, with the excess electricity fed to the grid.

The YB series box-type substation is a compact complete set of electrical equipment and devices that combine high-voltage equipment, transformers, low-voltage electrical equipment, etc.

The combined box-type transformer is to put the transformer body, high-voltage load switch, fuse and other components in the transformer oil tank together, because of immersion in oil, the volume of the components is greatly reduced, the structure is more compact, and the installation is convenient and flexible.
