Abstract
A dry-type transformer core has an iron core with a number of limbs designed to be wrapped with a winding and interconnected by a number of magnetic yokes. The object is to produce a transformer of this type in a simple manner, which is especially well protected against corrosion. For that purpose, the dry-type transformer core includes a casing that is formed onto the iron core. The casing surrounds the iron core in a substantially flush manner.
