What Taihan Electric Wire does

Taihan Cable & Solution Co., Ltd. (KRX:001440), branded internationally as Taihan Electric Wire, is a South Korean manufacturer of extra-high voltage (EHV) power cables, HVDC cable systems, submarine cables, and communication cables. Founded in 1955 (incorporated 1962) and headquartered in Seoul/Anyang, the company supplies 132kV through 525kV XLPE and oil-filled cables for utility transmission, plus 500kV current-source and 525kV voltage-source HVDC systems certified by KEMA — the latter being the highest commercially available HVDC voltage class globally. Its product portfolio also covers MV/LV distribution cables, industrial specialty cables, busducts, ACCC/ACAC high-capacity overhead conductors, submarine cables (up to 640kV HVDC-rated in development), solar and offshore wind cables, and copper and fiber-optic communication cabling, with copper rod and wire produced in-house as base material.

The company's competitive position is built on three technical differentiators: (1) certified 500kV/525kV HVDC technology (first in Korea, second globally for 500kV), (2) proprietary small-diameter insulated conductor technology delivering ~20% higher transmission capacity, and (3) vertically integrated submarine cable manufacturing with in-house installation capability through the Dangjin submarine cable plant (Plant 1 operational, Plant 2 under construction for 640kV HVDC) and dedicated cable-laying vessels PALOS and Skandi Connector. Manufacturing is anchored in Korea, with overseas plants in Vietnam (Taihan Cable Vina, including a 400kV UHV plant under construction), South Africa (M-TEC), and Kuwait (joint venture), supported by sales offices in the US, UK, Netherlands, Denmark, Sweden, and Germany. The company holds ISO 9001/14001/45001, UL, KS, and ESG A-grade certifications and carries an AAA credit rating from Korea's three major rating agencies.

Commercially, Taihan operates a turnkey project model — design, supply, installation, connection, and testing — sold through competitive bidding to national and state-owned utilities and large renewable developers. Named customers include SP PowerAssets (Singapore), National Grid (UK), Transgrid (Australia), TenneT (Germany), Energinet (Denmark), KEPCO (Korea), the Kuwait Public Authority for Housing Welfare, PSEG and PG&E (US), and Anma Offshore Wind (Korea). Pricing is project-based and not publicly disclosed, with individual contracts ranging from ~KRW 45 billion to over KRW 140 billion and cumulative Singapore wins exceeding KRW 1 trillion over two years. Taihan became a subsidiary of Hoban Group in 2021 and, following the 2023 leadership transition, is now led by Vice Chairman Song Jong-min.
