What DAEWON CABLE CO LTD does

Daewon Cable Co., Ltd. (대원전선주식회사, KSE: 006340) is a South Korea-based manufacturer of power, telecommunications, and specialty cables, founded in 1964 and publicly listed since 1988. The company produces a comprehensive product portfolio spanning low-voltage to medium-voltage power cables (CV, CVV, CCVV, TFR fire-resistant series, Neo-Cable), aluminum overhead conductors co-developed with KEPCO, communication cables (LAN/CAT.5-6, UTP, optical fiber Loose Tube and FTTH), automotive wires, and F.E.D field products for the US Army Corps of Engineers Far East District. Core technology centers on XLPE-insulated cable manufacturing, fire-resistant and flame-retardant cable formulations, and medium-voltage power transmission products, with the R&D laboratory operational since 1987.

The company generates revenue through direct hardware sales across four primary streams: power cables (serving KEPCO and industrial customers), communication cables (serving KT and telecom operators), automotive wires (via group subsidiaries Daewon F.M.I and Keumwon Cable in China), and international exports. Its go-to-market is enterprise field sales through five regional Korean offices (Seoul, Daejeon, Daegu, Gwangju, Busan), supplemented by direct export distribution to Asia, Oceania, Africa, and the Americas, and public tender participation for Korean government infrastructure projects. Pricing is project-based and contract-based rather than list-price, consistent with B2B industrial cable procurement.

Daewon Cable holds an extensive certification portfolio including UL (across more than 20 specifications), CE, KEMA, TRCU, KEPIC nuclear qualification, KS, KTC, Telcordia, and ISO 9001/14001, with co-development partnerships with KEPCO on next-generation power cables and supply relationships with Samsung Electronics, KT, and the US military. The group operates manufacturing facilities in Yesan (Chungnam), Iksan (Jeollabuk-do), and Shandong, China, alongside adjacent subsidiaries in aluminum wheels, plastic injection, and renewable energy. The company has been recognized with the One Hundred Million Dollar Export Tower (2012) and the Silver Tower Order of Industrial Merit (2007), and its stock has surged sharply in 2026 amid AI data center power infrastructure demand.
