The problem of lightning intruding overvoltage of submarine cable has an important influence on design, operation and manage-ment of China Southern Main Power Grid&Hainan Power Grid Interconnection Project. Based on EMTP/ATP, overvoltage levels of the 500 kV submarine cable due to shielding failure and back striking of the incoming aerial wires are calculated and analyzed. The value of lightning withstand voltage of the 500 kV submarine cables is calculated and measures for safety margin improvement are proposed. The research re-sults provide a reference for determination of lightning impulse level as well as design and operation of submarine cables.
