ZGS11 series combined transformer (also known as American box-type transformer substation) refers to install the high-voltage load switch, plug-in type fuse and high-voltage current-limiting fuse in the transformer box for insulation and cooling with the mineral oil. It has the advantages of reasonable and compact structure, small volume, flexible installation, convenient operation, small floor area and so on. It is applicable for the load center of urban power network, so as to reduce loss and improve power supply quality.

1. Small volume, compact structure and convenient installation.
2. Fully-sealed and fully-insulated structure, which can guarantee personnel safety;
3. It can be used for the ring network as well as the terminal. Conversion is convenient, and reliability of power supply is improved.
4. Low loss, low noise and superior performance.
5. The cable joint has the plug-in type, which has the features of the isolating switch, convenient and flexible operation.
6. High-voltage double-fuse protection. The plug type fuse has temperature and current double sensitive protection feature.
7. The backup fuse protects transformer failure and secondary line failure.
8. Anti-theft structure is adopted for the box.
9. Low temperature rise and strong overload capacity.
10. The transformer has the special structure, and the outstanding advantages are high voltage quality and small neutral point offset.
