Power & Industrial Systems - Hyosung will develop the world's best technology to enrich our everyday lives.

PRODUCT INDEX

Endless challenge for the best R&D competence

Hyosung has been recognized for its world-class technology in the field of high-voltage power systems as it developed Korea's first 765kV high-voltage transformer and 800kV gas insulated switchgear. Since its establishment in 1978, Power & Industrial Systems R&D Center has taken the initiatives in technical development in the field of heavy electric machine.
More recently, to respond to the new paradigm of the power industry represented by DC grid, it is spurring the development of new technologies, including ESS, STATCOM and voltage HVDC.
It is also developing IE4 grade super premium high efficiency motor to improve the efficiency of motors, which are the essential factor for automation in every industrial area and also account for 60% of energy consumption. In addition, the company strives to build and develop asset management solutions that provide systematic management services of facility assets combined with the fourth industry technology-based products service systems.
