Hosted by Korea Electric Power Corporation, BIXPO is Korea's largest global energy expo, bringing together companies and experts in the power and energy sectors to exchange the latest technologies. This year, around 200 companies from Korea and abroad took part under the theme "Tech Innovation meets Possibility."

Taihan Cable adopted the concept "From the West Sea to the World: The Future Growth Highway Built by Taihan Cable" for this year's exhibition. It set up three themed zones - turnkey submarine cable solutions, HVDC (high-voltage direct current) cable solutions, and new technologies and products - to showcase its technological capabilities and project execution expertise.

The exhibit that drew the most attention was a 345-kilovolt (kV) high-capacity transmission cable being jointly developed with Korea Electric Power Corporation. The product increases the maximum conductor cross-sectional area of existing 345-kV extra-high-voltage cables from 2,500 mm² to 3,200 mm². With the larger conductor cross-section, it can significantly increase transmission capacity along the same power grid route. It is regarded as a key product that could help cut construction costs and shorten construction times as the country expands its transmission lines. Taihan Cable is also developing related components, including extra-high-voltage cable joints that connect to the cable itself.

At the front of its booth, Taihan Cable displayed a 525-kV HVDC submarine cable that could be used in the West Coast Energy Highway project, along with models of the vessels Taihan Connector and PALOS, which recently had their names changed. The company also presented a large-scale video and messages highlighting its commitment to participating in the West Coast Energy Highway project and its vision for the future.

The company also highlighted its submarine cable production capabilities. It introduced Subsea Cable Plant No. 1, which supplied cables for major projects, including the Yeonggwang Nagwol offshore wind farm, and provided an update on Subsea Cable Plant No. 2, which is under construction with operations targeted to begin next year. Taihan Cable also showcased its internationally certified 525-kV voltage-source HVDC cable system and its HVDC Test Center, which can test HVDC cables rated up to 640 kV, underscoring its technological and testing capabilities.

Kim Junseok, president of Taihan Cable, attended the opening ceremony and toured the exhibition hall. He reviewed global power grid technology trends and met with representatives of key customers in Korea and abroad to discuss in depth ways to cooperate as transmission and distribution networks expand.

A Taihan Cable representative said, "This exhibition is an important opportunity to showcase the technological capabilities and project execution expertise we have built up in submarine cables and HVDC." The representative added, "We will actively respond to national core power grid projects, including the West Coast Energy Highway, and further strengthen our competitiveness in the global power infrastructure market through continued technological advancement."
