Wound iron core for static apparatus, amorphous transformer and coil winding frame for transformer

A coil winding frame for a transformer disposed on an innermost circumference of a coil into which an iron core is inserted, the coil winding frame having an enhanced strength with respect to buckling toward an inner side in a dented manner.

A shell-type amorphous transformer equipped with an amorphous iron core and a coil, wherein

• a side bracket for connecting a lower bracket for receiving load of the coil and the amorphous iron core and an upper bracket having a lifting lug for suspending the transformer is composed of a main face plate and two side face plates disposed along an outer side surface and both width-direction side surfaces of the amorphous iron core;
• and
• an insulating iron core support panel is passed through a pair of or multiple pairs of holes formed at opposing areas of the both side face plates along an inner side wall of the amorphous iron core.
