Abstract (en)
[origin: WO2016050515A1] The invention relates to a dry-type transformer core (1) comprising an iron core (2) having a number of limbs (8) designed to be wrapped with a winding and interconnected by a number of magnetic yokes (10). The aim of the invention is to produce a transformer of this type in a simple manner, which is especially well protected against corrosion. To achieve this, the dry-type transformer core (1) comprises a casing (4) that is formed onto the iron core (2), said casing surrounding the iron core (2) in a substantially flush manner.
