345kV OF 케이블 보통접속재의 절연설계에 관한 연구

A Study on the Insulation Design of Normal Joint in 345kV Oil-Filled Cable

This paper presents the insulation design of 345kV OF cable normal joint which is essential to construction of underground transmission system. The insulation designs of stress relief cone, pencilling and sleeve were proposed in this paper, and the final insulation design was decided by the results of the electric field and thermal analysis using FEM. It is shown that the designed normal using proves the effect when the developing test is carried out to construct 345kV OF cable if the domestic underground transmission system.
