Electrical steel, which is in turn graded by wattage loss, is used for the manufacturing of transformers in accordance with DIN EN 10106 and EN 10107.
The electrical steel is divided into grain-oriented and non-grain-oriented strips.
Grain-oriented strips are characterised by lower wattage loss, but are more expensive to manufacture. Applications which require high output at low volumes are preferentially realised using lamination cores made from grain-oriented electrical steel.
Non-grain-oriented strips are
usually used to manufacture mains transformers with lower outputs.
