Hyosung Heavy Industries

Hyosung Heavy Industries was originally established in 1962 as HanYoung Industrial Co., Ltd. In 1969, it developed Korea's first 154kV extra-high-voltage transformer. The company was renamed as Hyosung Heavy Industries Corporation in 1977. Throughout the 1980s and 1990s, the company expanded its operations in power solutions and circuit breakers. In 2018, it was spun off from the Hyosung Corporation as an independent entity. Since 2019, the company has invested heavily in hydrogen energy and digital solutions to enhance its technological capabilities.

In 2020, Hyosung Heavy Industries signed a memorandum of understanding with Linde Group to cooperate on liquid hydrogen production, storage, and distribution. In 2024, the company announced the commercialization of a 100% hydrogen engine generator.

The company's headquarters is located in Seoul, South Korea. It also operates manufacturing plants in Changwon, South Korea. Additionally, the company has a global presence with locations in China, India, Vietnam and the United States.

Business Areas

Power Solutions

Hyosung Heavy Industries has the highest cumulative market share in Korea's power transmission and distribution sector. The company produces power equipment including extra-high voltage transformers, extra-high voltage circuit breakers, and electrical components, while providing engineering, design, manufacturing, installation, testing, and maintenance services for power equipment.

Major products include power equipment (extra-high voltage transformers, distribution transformers, shunt reactors, extra-high voltage circuit breakers, switchgears, mobile substations), power systems (STATCOM, DC transmission and distribution systems, ESS, microgrids, solar power solutions), digital solutions (power equipment asset management solutions, preventive diagnostic systems), and welding solutions (arc welders, resistance welders).

In 2024, the company completed development of a 200MW ultra-high-voltage direct current (HVDC) transformer. The HVDC transformer manufacturing plant is scheduled to be built in Changwon, South Gyeongsang Province, and is scheduled for completion in 2027.

Electrical & Mechanical Solutions

The company produces a range of motors from low-voltage small and medium-sized motors to high-voltage ultra-large motors, super-premium efficiency motors, BLDC motors, and Q-Class motors for nuclear power plants. In the generator sector, the company manufactures and exports power generation systems for ships, steam turbines, and water turbines, as well as MG-Sets for fuel rod control to overseas nuclear power plants. Major products include motors & generators (high-voltage motors, low-voltage motors, DC motors, special motors, commercial generators), industrial machinery systems (chemical equipment, gas charging stations), and gear solutions (gearboxes, geared motors).
