Industries such as high power rectifier systems for electrolysis, arc furnaces, HVDC converter stations, semiconductor fabrication plants, large UPS systems, and test laboratories frequently need custom power transformers. They may require particular leakage reactance, multiple secondaries, complex cooling arrangements or integrated monitoring. Environmental conditions such as offshore, desert or arctic locations also drive custom mechanical and insulation designs. In these sectors transformer performance and reliability are tightly linked to process continuity and product quality.
