The pad-mounted transformers, (commonly known as the American transformer) incorporate the body of trans-former, switch device,and fuse,tap changer, and other accessories.There are two types: terminal type and ring type.The two types could apply to different grid systems.With compact structure, small size, low investment, and fast installation, it could be used outdoors as well as
indoors, for example, residence, airport, apartment, commercial center, mines, hospital and school etc. It could be applied in the loading center and improve the power supply. It could also satisfy such requirements as the consumption metering, reactive compensation, and Low voltage shunt.It is easy to operate.

●Its fully insulated structure and interlocking devices ensures the safety,of users.
●It' s completely sealed structure, free from oil aging,extends service life.
●Its load switch with characteristics of three-phase gear,effectively reduces the ferromagnetic resonance.
●Its double fuse protection ensures simple, convenient,economic, reliable and safe operation of the system.
●With alternatives like silicon steel core, amorphous alloy core, wound coiled core,etc,it has low loss,low noise,and low temperature for tank.
●HV inlet uses plug-in cable sealing end, with 200A loading current.In case of emergency, it could work as the load switch,so like the character of isolating switch.
●It is small in size,only about 1/3 of European style trans-former.
