摘要：
This transformer core comprises superposed groups of amorphous steel strip wrapped about the core window, each group comprising an inner section and an outer section disposed in superposed relationship, and each section comprising many thin layers of amorphous steel strip. Each of the layers in a section has a length dimension measured between the transversely-extending edges of the layer located at opposite ends of the section. The layers in the inner section of a group have substantially equal lengths, and the layers in the outer section of said group have substantially equal lengths of a greater value than the lengths of the layers in the inner section. At one end of each group the transversely-extending edges of all the layers in said group are substantially aligned to form a smooth edge. At the other end of the group (i) the transversely-extending edges of the layers in the inner section are disposed to form a beveled edge for the inner section, (ii) the transversely-extending edges of the layers in the outer section are disposed to form a beveled edge for the outer section, and (iii) the beveled edge of the outer section overlaps the beveled edge of the inner section.
