ABSTRACT:
A transformer with E-shaped and I-shaped magnetic cores which are respectively formed of a stack of E-shaped sheet laminations and a stack of I-shaped sheet laminations, includes sheet insulators to insulate coils from the magnetic core. Spacer members are formed from parts of the sheet insulator to hold the preferable distance between the coil and a central leg of the E-shaped magnetic core. The spacer members are each formed by folding parts of the sheet insulator.
