Signing a joint research project agreement with KAIST Korea Electric Power Corporation (CEO Jeong Seung-il) held a joint research and development agreement ceremony with participating organizations to secure technology for manufacturing and continuous production (mass production) of graphene fiber-based ultra-light and large-capacity power cables at KAIST on the 15th. did. Due to the increase in the generation of new and renewable energy sources in accordance with the governments 2050 carbon neutrality policy, it is necessary to supply electricity by increasing the transmission capacity compared to the existing one. This research project was initiated because it was necessary to develop a new material power line that uses the existing transmission line but can increase the transmission capacity by replacing only the power line.

[Photo = KEPCO] Currently, KEPCO uses an aluminum conductor steel reinforced (ACSR) wire composed of aluminum (the part that flows current) and steel (the part that maintains tensile strength), which is a metal material. is in one state The worlds attention is focused on the development of new power lines using new materials rather than metal materials. As a technological alternative, KEPCO plans to promote the development of graphene fiber-based power wire rods and technology for large-scale production. The graphene fiber-based ultra-light and large-capacity power line is a new material power line that can increase the power transmission capacity three times or more compared to the existing aluminum material power line and is light in weight. It will be carried out for 30 months from March 2022 to August 2024. We will promote joint research and development through solidarity and cooperation by maximizing the experience and capabilities of each institution. KEPCO plays a role in developing performance evaluation technology and systems for graphene composite fiber materials. KAIST is responsible for the development of the continuous manufacturing complex of graphene fibers and the manufacturing process for stranded fibers.
