Specifications

Variable Speed Drives transformers
 
Our combination transformer, (also called American box transformer) combines the body of transformer, switch, and fuse, and other accessories.
There are two high voltage load switches; terminal and ring which could apply for different distribution network systems. It is compact, small and quick to install.
It could go into the charge center, improve the power supply. It could also satisfy the requirement as the calculation of consummation, reimbursement, low voltage division. It is easy to operate.
 
Application of Variable Speed Drives transformers
 
It could be used outdoors as well as indoors, for example; In residential area, airport, apartment, commercial center, mines, hospital and school etc.
Main Characters of Combination Transformer:
Main Characters of Application of American Box Transformer:
1• All insulated structure and interlocking devices to ensure safety.
2• All sealed structure, free from oil quality degeneration, prolong the life of transformer.
3• Charging switches are interacted in three phased which reduces the resonance of iron and magnet;
4• Double fuse protection, to assure the system simple, convenient, economical and reliable;
5• Silicon steel core, amorphous alloy core, coiled core etc; low loss, low noise, and no temperature raising on box surface;
6• High voltage line plug cable is elbow style and can operation 200A charging current.
In emergency, it could operate the charging switch. It could be insulated from switch.
7• Small size, only 1/3 of European style box.
