Product description
Overview
The combined transformer (also called as American-type box substation) refers to uniformly designing the transformer body, high-voltage load switch, fuse for protection and other equipment, placing them in the same sealing oil tank, and providing the complete operation viewing instrument pressure gauge, pressure relief valve, oil level gauge, oil temperature gauge and others. The American-type box substation has reliable power supply, reasonable structure, rapid installation, flexibility, easy operation, small volume, low cost and other excellent performances, can be used in both outdoors and indoors, and is widely used in the industrial park, residential quarter, commercial center, high-rise building and other various occasions. 
 
Characteristics of American-type box substation:
1. It has full-sealing and fully insulated structure, with no need for the insulation distance, thereby reliably protecting the personal safety.
2. It has small volume and compact structure, and is only about 1/3 of domestic box transformer. 
3. It can be used in both looped network and terminal, therefore, the transformation is very convenient, thereby improving the flexibility of power supply. 
4. It has small loss, and has the same loss as that of the domestic transformer with the same model. The combined transformers with the loss level for 9 series, 10 series, 11 series and amorphous alloy core series can be provided according to the customer needs for selection. 
5. The cable joint can operate 200A load current, can be operated as the load switch in case of emergency, and has the characteristics of disconnector, therefore, the operation is convenient and flexible. 
6. It adopts the double fuse protection, therefore, the operation is reliable. 
7. The anti-corrosion design and special paint treatment are adopted by the box, therefore, it can be widely used in the various bad environments, such as high pollution areas having much rainstorm.
