Hyosung Heavy Industries said on the 8th that cumulative production of extra-high-voltage transformers at the Changwon plant has surpassed 10 trillion won. It is the first case in Korea in which both transformers and circuit breakers produced at a single plant have each exceeded 10 trillion won.
Hyosung Heavy Industries developed Korea's first 154-kilovolt (kV) extra-high-voltage transformer in 1969 and began production. Following 154 kV and 345 kV extra-high-voltage transformers, in 1992 it independently developed a 765 kV extra-high-voltage transformer, the world's sixth and the first in Korea. The cumulative production value of extra-high-voltage transformers exceeded 1 trillion won in 2002, 5 trillion won in 2014, and 10 trillion won in January this year.
On the strength of its proprietary technology over the past 50-plus years, Hyosung Heavy Industries now supplies customized products to about 70 countries worldwide. In the U.S. market, it has maintained the No. 1 share for 765 kV transformers since the early 2010s, and in major European transmission markets with high technical barriers, including the United Kingdom and Norway, it also holds the No. 1 share for 400 kV transformers.
With an expansion in global orders, the Changwon plant has recorded more than 1 trillion won in annual orders for the single item of extra-high-voltage transformers for three consecutive years since 2023.
Hyosung Chairman Cho Hyun-joon said, "Achieving 10 trillion won in transformer production is the result of the trust built with customers and the Changwon plant's determination to pursue 'top quality,'" adding, "We will further strengthen our total solution capabilities in transformers, circuit breakers, and HVDC to cement global market trust."
