Hyosung Heavy Industries is pushing into the U.S. power infrastructure market tied to growing electricity demand from AI data centers, highlighting a next-generation solid-state transformer (SST) it says is a world first. The company reports developing a 22.9-kilovolt (kV), 1.05-megavolt-ampere-class SST in 2022 designed for direct connection to urban distribution networks.
Both outlets describe SST technology as using power semiconductors to precisely control voltage and current while keeping insulation functions similar to conventional transformers. Hyosung links the product to needs for stable, efficient power delivery as utilities seek to modernize and replace aging grid facilities. The Korea Times emphasizes the market driver—AI-driven demand for electricity and the expansion of data-center infrastructure—while the PR Newswire focuses on execution in the U.S., saying Hyosung has completed local production bases for transformers and breakers there.
Together, the coverage indicates Hyosung is combining its SST technology with increased U.S. manufacturing capacity to compete in high-voltage power equipment, with the company led by Chairman Cho Hyun-joon.
