Combination Transformer

These Combination Transformers, (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, and small, cheap, quick to install. It could be used outdoors as well as indoors, for example; residence, airport, apartment, commercial center, mines, hospital and school etc. 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.

Main functions and characters:
a c All insulated structure and interlocking devices, safe
a c All sealed structure, free from oil quality degeneration, prolong the life of transformer.
a c Charging switches are interacted in three phased together which reduces the resonance of iron and magnet;
a c Double fuse protection, to assure the system simple, convenient, cheap and reliable;
a c Silicon steel core, amorphous alloy core, coiled core etc; low loss, low noise, and no temperature raising on box surface;
a c Input wire of high voltage is with elbow form connection. Could operation 200A charging current.
In emergency, it could operate the charging switch. It could be insulated from switch.
a c Small size, only 1/3 of European style box.
