The utility model relates to an open triangle transformer iron core, which particularly consists of three same iron core columns, an upper iron yoke and a lower iron yoke that are in butt joint. Eachiron core column is formed by superposing silicon-steel plates with the same length and the different widths in each group; the cross section of each iron core column takes the stepped shape and is arranged in a circumcircle; and the upper iron yoke and the lower iron yoke are the same triangle frames formed by winding silicon-steel plates with equal width. A transformer made of the iron core hasthe advantages of light weight, less iron loss, low noise, convenient winding and the like.
