Two- or multi-phase transformer

The invention relates to a two- or multi-phase transformer with a a web and at least two legs having the yoke, through which legs each have a coil (17) is set, and at least one carrier, on which the web is fixed and the bearing surfaces (14) comprises for the coils. On each bearing surface (14) are at least two supporting blocks (15, 16) mounted for each coil on the coil side support surface (19) with elastic compensating elements (35) are occupied and extending at their perpendicular to the supporting surface (19) longitudinal side surfaces (25 , 26) at least one lengthening the creepage distance bar (27, 28) in the longitudinal direction and parallel to the supporting surface of the supporting block having himself.
