Taihan Cable & Solution has secured a 146.3 billion won ($96.5 million) contract for a key national power transmission project, strengthening its position in the fast-growing high-voltage direct current, or HVDC, market as Korea pushes to expand long-distance electricity networks.

The company said Wednesday that it won an order for the second phase of Korea Electric Power Corp.’s 500-kilovolt HVDC Donghaean-Dong Seoul transmission project.

Under the turnkey contract, Taihan Cable will manufacture, supply and install 500-kilovolt HVDC XLPE cables and related equipment for the project.

The Donghaean-Dong Seoul HVDC network is designed to transport electricity generated by nuclear, thermal and renewable energy facilities along Korea’s east coast to the Seoul metropolitan area, where power demand remains concentrated.

As part of the project, Taihan Cable will supply and install approximately 86 kilometers of 500-kilovolt HVDC XLPE cable systems.

The contract marks another milestone in the company’s effort to expand beyond conventional transmission systems and deepen its presence in advanced power infrastructure.

Taihan Cable said it previously developed and commercialized Korea’s first 500-kilovolt HVAC cable system and later succeeded in developing Korea’s first 500-kilovolt current-source HVDC cable system and 525-kilovolt voltage-source HVDC cable system under high-temperature operating conditions.

The company said those technologies have been designated as national core technologies.

A company official said the contract reflects years of investment in HVDC technology, manufacturing and construction capabilities.

The official said Taihan Cable plans to leverage its domestic project experience to pursue additional opportunities, including the proposed West Coast Energy Highway project and other large-scale power grid developments in Korea and overseas.
