Power Transformer

Since 1969, when Hyosung Heavy Industries developed the 154kV transformer for the first time in South Korea, it has been manufacturing and operating ultra-high-voltage transformers up to 765kV. Hyosung Heavy Industries supplies a wide range of transformers up to 765kV and 1500MVA, both with core form and shell form technology. As a result, the company has the capacity to offer a wide range of solutions to customers, with extensive project experience in over 70 countries around the world and supplying over 6000 units of power transformers from Changwon, Korea alone. In fact, we are a global transformer brand, with the capacity to satisfy standards of each country and international standards, such as IEC, ANSI, IEEE, NEMA, BS, JIS, JEC, etc.
