The utility model discloses an amorphous iron core transformer in transformer field, including the iron core, and center on the low voltage coil and the high -pressure coil of the iron core column section setting of iron core, on the width direction of iron core, the thick both ends of following of folding of iron core increase to middle gradient. Its technological effect is: can make low voltage coil and high -pressure coil's coiling more docile, the width of cloth is better to size control, can improve amorphous iron core transformer's reliability and anti short circuit ability, can so that amorphous iron core transformer's load noise be effectively controlled.
