Abstract

1. A winding for a dry transformer or reactor, in which the hollow space between at least two winding layers (1, 2) is divided into a plurality of axially extending cooling channels by an axially aligned spacer assembly, with the spacer assembly including supporting legs interconnected with a spacing from each other, characterized in that in the spacer assembly, two of the supporting legs (4, 5; 4b, 5b; 4c, 5c; 4d, 5d) each terminate freely and are rigidly interconnected in pairs to define separate distance elements (3).
