Abstract

The disclosure relates to a transformer having a yoke which has a crosspiece and at least two limbs, over which limbs a coil is placed in each case, and having at least one carrier on which the crosspiece is fixed and which has bearing faces for the coils. At least two supporting blocks for each coil are mounted on each bearing surface. The supporting blocks are fitted with elastic compensation elements on the coil-side carrying face and have, on their longitudinal side faces, which run perpendicular to a carrying surface, at least one strip which extends the creepage path and runs in the longitudinal direction and parallel to the carrying surface of the supporting block.
