COMPLETION OF 345kV LONG DISTANCE XLPE CABLE

345kV XLPE 장거리 지중송전선로 준공

345kV XLPE Cable system was constructed between Yeongseo-Yeongdeunpo at first in Korea. XLPE cable have the advantage of OF cable. it is to raise the power transmission capacity and reduce the power loss and expenses. We also applied many new technology in this project at first. One is pre-fabricated joint which can be easily assembled in the field without any hand-skill, another is PD(Partial Discharge) test for after laying test. Especially, PD measurement for after-laying test was performed to evaluate the quality of the cable joint and termination. Through the good experience of this project, we have gotten the international competitiveness of power business.
