High voltage transmission and transformation
(66kV ~ 765kV) construction

We are carrying out the turn-key project of underground cable lines based on our knowledge and experience in high-voltage underground transmission and transformation (66kV ~ 765kV), which is the artery of the national key industry. Based on this, we provide complete services for specialized engineering, design, construction and post-construction management. In recent years, there is a tendency to improve the quality of cable accessories and to make plug-in for simplification of construction. Accordingly, EPE received a certificate of Pfisterer, SWCC Showa, and NKT connection construction through self-access education and overseas training. Through these experiences, EPE have provided the best possible solutions for projects such as Korea Electric Power Corporation (KEPCO) in Korea, Sakhalin Energy Investment Company (SEIC) in Russia, OPF SITE PJT (Worlet Parsons Group) in UK and SEIC LNG site (Chiyoda) where we could have lots of experiences in construction with quality.

Specializing in Underground Transmission
(2011.1.3 KEPCO)

EPE has acquired the qualification as an underground transmission construction company due to the separation of construction contract from jointed contract of material supply & underground transmission construction which was limited to only the cable & accessories companies in KEPCO, Thereby we have been providing even better construction quality. image
