🇩🇪 Transformer Industry — Germany

Germany is the engineering heart of the European transformer industry. It is a demanding market for high-efficiency, low-loss distribution and power transformers, shaped by EU eco-design (Tier requirements), aggressive renewable integration and the TSO-led grid reinforcement of a 50 Hz ENTSO-E network.
