The utility model discloses an aluminum foil coil and an active part of an amorphous alloy dry-type transformer, which includes a three-phase amorphous alloy iron core, a high-voltage and a low-voltage coils arranged on an iron beam, upper clamp parts arranged on the upper end of the high-voltage and the low-voltage coils, an insulating framework arranged on the iron beam and a plurality of aluminum-copper transition connectors fixed on the upper clamp parts by insulation line clamps or insulating terminals. The conductive material of the low-voltage coil is aluminum foil and is directly wound on the insulating framework; the head and the tail ends of the low-voltage coil are respectively fixed on and connected with the aluminum-copper transition connectors; the high-voltage coil is wound by a copper wire and sealed by epoxy resin, and arranged on the outer surface of the low-voltage coil. The technical proposal of the utility model is that the copper is replaced by aluminum, and the aluminum foil coil and the active part of amorphous alloy dry-type transformer not only is characterized by low no-load loss of a general amorphous alloy distribution transformer, but also has the advantages of low material cost, light weight, reduction of impact of the rising copper price on the cost of the amorphous alloy distribution transformer, reduction of consumption of copper resource in shortage, etc.
