Taihan Secures Korea’s First Extra-Long Continuous Underground Power Grid Project
Taihan has won a groundbreaking project commissioned by Korea South-East Power Co. to build Korea’s first underground power grid using extra-long continuous cable technology. The project involves connecting the Goseong Natural Gas Power Plant and the Shingoseong Substation in Goseong County, Gyeongsangnamdo Province, with a 345kV extra high-voltage underground power grid. Taihan will oversee the entire process, from manufacturing and transporting extra high-voltage cables and cable accessory to cable installation and electrical construction.
This project marks a significant milestone as it introduces extra-long continuous cable technology in Korea for the first time. This advanced technology enables the production and installation of cables longer than 1 km in a single stretch, more than doubling the 500-meter average production length previously used in the country. Korea South-East Power adopted this method to catch up with advanced overseas technologies and implement cutting-edge infrastructure domestically.
By using this technology, the need for intermediate cable joints is eliminated, allowing a single cable to cover the entire grid section. This approach reduces manufacturing and construction costs, shortens construction timelines, and enhances efficiency. Furthermore, it minimizes the risk of faults, thereby improving the reliability of power supply.
Taihan attributes its success in securing this project to its proven track record in similar undertakings, such as a large-scale extra-long continuous cable grid project in Singapore. In that project, Taihan successfully constructed a 400kV underground power grid, Singapore's highest voltage level, using cables with lengths of approximately 1.9 km. The project, conducted over three years from 2016, demonstrated Taihan’s advanced expertise in extra-long continuous cable technology and bolstered its reputation both domestically and internationally.
