Product presentation
Combined transformer (also known as American box-type transformer) is a unified design of transformer body, high voltage load switch, protection fuse and other equipment, placed in the same sealed tank, equipped with complete operation inspection instrument pressure gauge, pressure release valve, oil level meter, oil temperature meter, etc. American box has reliable power supply, reasonable structure, rapid installation, flexible, easy to operate, small size, low cost and excellent performance, can be used outdoors, but also can be used indoors, widely used in industrial parks, residential areas, commercial centers and high-rise buildings and other places
Product features
1,Fully sealed, fully insulated structure, don’t need insulation distance, a reliable protection of personal safety.
2,Small size, compact structure, only about 1/3 of the same capacity of the domestic box in our country.
3,It can be used for both ring network and terminal, and the conversion is very convenient, which improves the flexibility of power supply.
4,The loss is small, and the loss of the same type of transformer in China is the same, according to customer needs,we can provide the loss level of 9 series, 10 series, 11 series and amorphous alloy core series of combined transformers to choose.
5,The cable connector can operate 200A load current, and can be operated as a load switch in emergency situations, and has the characteristics of isolation switch, convenient and flexible.
6,Using double fuse protection, operate reliably.
7,The box adopts anti-corrosion design and special spray painting treatment, which can be widely used in various harsh environments, such as high pollution areas with frequent storms.
