Taihan will begin making full-fledged efforts to extend its influence into the market of HVDC cable, which is rapidly growing worldwide.

Taihan announced on Dec. 5th that it has completed the development of a 500kV LCC (Line Commutated Converter) XLPE HVDC (High Voltage Direct Current) land cable system and obtained internationally accredited certification.

500 kV is the highest voltage among LCC XLPE HVDC cable systems developed. Taihan accomplished KEMA international certification as it is the first in Korea and the second in the world after Japan to complete KEMA internationally accredited certification for 500 kV LCC XLPE HVDC cable. KEMA international certification is an internationally accredited certification with which export and commercialisation without independent testing are possible.

HVDC has less power loss than AC (Alternating Current) and has no restriction in the transmission distance, so it is touted to be a key technology for long-distance large-scale power transmission. The demand for HVDC is growing internationally as the demand for inter-country power grid connection (Super grid) and new & renewable energy sources based on DC, such as solar power, wind power, and fuel cells, increase. According to industry experts, it is estimated that the global market size of HVDC cables will expand from KRW 70 trillion in 2020 to KRW 159 trillion in 2030.

In particular, HVDC, which is insulated with XLPE, has excellent insulation, heat resistance performance, and high durability, so the demand for HVDC is rapidly growing in advanced markets such as Europe and the United States.

Taihan successfully completed the 500kV LCC XLPE HVDC land cable system certification in the presence of KEMA Laps in the KEPCO Electric Power Research Institute’s Gochang Power Test Center. By obtaining this certification, Taihan is officially recognised for its technology and stability while at the same time securing an opportunity to participate in large-scale projects. In particular, this certification has high significance in that the test was conducted by applying technical specifications higher than international standards so that it can be immediately used in large-scale HVDC projects scheduled to be conducted in Korea.

Furthermore, Taihan also succeeded in the KEMA international certification test for VSC (Voltage Source Converter) 500 kV HVDC cable in addition to LCC XLPE 500 kV HVDC cable. As a result, Taihan is equipped with technical capabilities for 500 kV HVDC land cable systems of all conversion methods, such as XLPE LCC and VSC, including the 500 kV MI-PPLP (Mass Impregnated Polypropylene Laminated Paper) HVDC developed in 2017, which allows Taihan to be able to respond to the market actively.

President of Taihan, Na Hyeong-gyun, said: “It is very encouraging that Taihan has been recognised for its HVDC technology through international certification at a time when the global demand for long-distance transmission and the spread of new and renewable energy sources are becoming active. We will actively seek business opportunities in projects that are in full swing in Europe and the United States, etc., as well as participating in large-scale HVDC projects scheduled to be carried out in Korea.”

In addition, he added: “We will secure all technological capabilities related to HVDC and enhance competitive edge by completing the development of an HVDC submarine cable system as soon as possible by utilising the submarine cable seaside plant scheduled to be built in Dangjin, Chungcheongnam-do.”

Taihan judged that the demand for HVDC would continue to expand, selected HVDC cables as a key driving force for the company’s sustainable growth, and established a dedicated organisation in 2016. In 2017, it succeeded in developing a 500 kV MI-PPLP HVDC cable, jointly developed a new insulator material for HVDC cable accessories with Hwaseung Material Co., Ltd., a company specialised in manufacturing materials, and realised localisation of HVDC core materials and technological independence.​
