The ZGS series combined transformer (commonly known as American-type pad-mounted transformer) is a fully integrated compact distribution substation solution.

It combines multiple electrical components into a sealed oil-filled tank, including:

• High-voltage load switch
• Plug-in fuses
• Backup protection fuses
• Transformer core and windings
• No-load tap changer

The entire system uses transformer oil as insulation and cooling medium, ensuring safe and stable operation.
