Abstract (en)
[origin: EP1037220A2] A cast resin transformer (4) includes three sets of windings (1- 3) arranged in series and adjacent to one another. Of the three winding sets only the second winding set (2) has a cooling element (18,34). The second set of windings (2) includes a first winding (13) enclosed by a second winding (10) with provision for an inter- space (16) for accommodating the cooling element (18,34), which is specifically designed as a cooling cylinder (18), which contains a plastics material, or is completely made of plastics material or more specifically contains a metal.
