[Market Focus] Hyosung Heavy Industries Up 3% on Development of Gas-Insulated Circuit Breaker for US Export

Developed Using Korea's First Spring-Operated Mechanism

The share price of Hyosung Heavy Industries, which developed Korea's first spring-operated Gas-insulated Circuit Breaker (GCB) for export to the United States, rose by 3% compared to the previous day.

As of 9:51 a.m. on March 20, Hyosung Heavy Industries was trading at 2,775,000 won, up 3.04% (82,000 won) from the previous day. In early trading, the price climbed as high as 2,776,000 won.

On this day, Hyosung Heavy Industries announced that it had completed the development of the GCB for export to the United States and had also passed the certification test for the Institute of Electrical and Electronics Engineers (IEEE) standard, an organization that establishes international standards in the electrical and power sectors.

The GCB is a key safety device that helps manage loads on the power grid for stable operation and rapidly cuts off current in the event of an abnormality, preventing blackouts or equipment damage.

According to Hyosung Heavy Industries, the newly developed 362kV GCB is Korea's first to adopt a spring-operated mechanism. Compared to the conventional pneumatic operation method, it requires only one-fifth of the energy to operate, significantly reducing noise and increasing quality reliability. It can also be transported as a finished product, reducing installation time by more than 80% compared to previous models.

Hyosung Heavy Industries secured pre-orders worth over 100 billion won from U.S. customers from the development stage for this product.
