Hyosung Chairman Cho Hyun-Joon targets U.S. AI power market with 22.9kV SST
Hyosung Chairman Cho Hyun-Joon announced the development of the world's first 22.9kV Solid State Transformer (SST). This technology aims to give Hyosung a competitive edge in the next-generation power market. The company has also established local production facilities for transformers and breakers in the United States. This move solidifies Hyosung's presence in the American power equipment sector. The announcement was made on September 7, 2026, from Seoul, South Korea.
Hyosung's new 22.9kV Solid State Transformer (SST) positions the South Korean firm to capitalize on the growing energy demands of the U.S. AI sector. The company's established U.S. production bases for transformers and breakers reflect a direct strategy to serve this market. This is a concrete step to integrate advanced power solutions into critical infrastructure, moving beyond traditional transformers. The immediate impact for Asia is the demonstration of a Korean company leading in specialized power technology for a high-growth segment. The challenge will be scaling production and securing significant contracts against established players in the U.S. market, where local content rules and existing vendor relationships can be formidable. The 22.9kV SST's efficiency claims will need to translate into tangible cost savings and reliability for data center operators to truly disrupt the market.
