Distribution transformer stations with two voltage levels have windings from parts. So as to increase dynamic resistance of wndings, winding of higher voltage consists of four windings (2), (3), (4) and (5). Windings with conductors (17), (18), (19) and (20) are coupled with a selector switch (9). In comparison to the winding of lower voltage (1) the windings are axially arranged. Windings (2), (3) and (4), (5) have opposite directions of winding as those are coupled by conductors (12) and (13) in the way given in figure 2.
