Production and installation of over 1km cable at once
Increased construction efficiency and stability compared to 500m-long cable installations, ‘[E-Daily reporter Kim Seong-jin] Daehan Cable announced on the 15th that it has won the contract for Korea’s first ultra-long underground power grid project ordered by Korea South-East Power Company.’,
,
, ‘This project involves connecting the Goseong natural gas power plant and the new Goseong substation with a 345kV ultra-high voltage underground power grid in Goseong County, Gyeongsangnam-do. Daehan Cable will carry out the entire process of building the power grid, from the production of ultra-high voltage cables and power equipment to transportation, installation, and electrical work.’,
,
, ‘This project is significant as it applies ultra-long cable technology for the first time in Korea. Ultra-long cable installation refers to producing and installing cables over 1km in length at once, a high-difficulty technology that more than doubles the average cable length of approximately 500m previously used in Korea. Korea South-East Power decided to adopt this method to catch up with advanced overseas technologies.’,
,
, ‘Applying this technology allows the construction of the entire section of the power grid with a single cable, eliminating the need for intermediate connection boxes. This reduces production and construction costs, shortens construction time, and increases construction efficiency. Moreover, it reduces the likelihood of failures, thereby enhancing power supply stability.’,
,
, ‘Daehan Cable highlighted its experience in constructing ultra-long cable power grids in Singapore as the background for winning this contract. It was a large-scale project to build a 400kV ultra-high voltage power grid within a power tunnel, the highest voltage level in Singapore, with cable lengths reaching about 1.9km. Daehan Cable successfully completed this project, which ran from 2016 for three years, gaining recognition for its ultra-long cable technology both domestically and internationally.’,
,
, ‘A representative from Daehan Cable stated, “The ultra-long cable power grid method is expanding in advanced countries, providing more business opportunities as it can be applied to various projects at home and abroad in the future.” They added, “We will continue to develop technology optimized for customer and site requirements, enhancing global bidding competitiveness while increasing corporate and shareholder value.”’,
