Hyosung Heavy Industries Invests 100 Billion Won in Dedicated Ultra-High Voltage Circuit Breaker Plant

Targeting 2026: New Ultra-High Voltage Circuit Breaker Plant in Changwon
Pune Plant in India Also Expanding; Production Capacity to Increase by 1.5 Times
"Total Power Solutions Prepared to Meet Surging Demand"

Hyosung Heavy Industries is expanding its ultra-high voltage circuit breaker production facilities to meet the growing global demand for power infrastructure. The company is simultaneously building a new plant in Korea and expanding its existing facility in India, marking a full-scale entry into the global market.

On September 24, Hyosung Heavy Industries announced that it will invest a total of 100 billion won to construct a new dedicated export ultra-high voltage circuit breaker production plant in Changwon, South Gyeongsang Province, and to expand related production lines. The new plant is scheduled for completion in the first half of 2026. Once completed, the company’s ultra-high voltage circuit breaker production capacity will increase by approximately 1.5 times compared to current levels.

The new Changwon plant will manufacture ultra-high voltage circuit breakers of 420kV, 550kV, and 800kV, supplying major markets such as the United States, Europe, and the Middle East. Alongside the production lines, the company will also expand facilities for manufacturing and testing insulation materials, which are core components of circuit breakers, aiming to enhance product reliability and export competitiveness.

This investment is a strategic move targeting the growth of the global circuit breaker market, driven by a surge in power demand due to the expansion of data centers and the artificial intelligence (AI) industry, as well as increased demand for the replacement of aging power grids in developed countries. According to market research firm Fortune Business Insights, the global circuit breaker market is expected to grow at an average annual rate of 8.3%, from $22.47 billion (approximately 30.3 trillion won) in 2024 to $42.85 billion by 2032.

Hyosung Heavy Industries is also expanding its operations in India, a key global power infrastructure market. The company plans to increase the production capacity of its local Pune plant to respond to rapidly growing demand. India, the world’s third-largest electricity producer, is expanding its share of non-fossil fuel power generation by 2030, and as a result, projects to expand and modernize transmission and distribution networks are actively underway.

With this investment, Hyosung Heavy Industries aims to broaden its position as a comprehensive power solutions provider, supplying not only circuit breakers but also STATCOM (Static Synchronous Compensator) for grid stabilization, high-voltage direct current (HVDC) transmission facilities, compact gas-insulated switchgear (C-GIS), and energy storage systems (ESS).

Hyunjoon Cho, Chairman of Hyosung, stated, "Securing sufficient production capacity to handle incoming orders is essential to meet the growing global demand for power infrastructure. In the future, we will deliver tangible results with total solutions, including ultra-high voltage circuit breakers."
