The utility model relates to a 500kV and following submarine cable are with big cross -section copper conductor that blocks water belongs to submarine cable conductor technical field. The utility model discloses a circular copper single line, heterotypic copper single line and the filler material that blocks water, heterotypic copper single line are " Z " type copper single line or " T " type copper single line, and circular copper single line carries out sticising the first time transposition, and special -shaped copper single line carries out secondary transposition shaping. The utility model discloses a having adopted the transposition of soft round copper wire and heterotypic copper line secondary, having realized that conductor ensemble average sticiss the coefficient and reaches morethan 92%, the conductor sticiss the degree and improves greatly, abnormal shape line transposition in -process has adopted the molded lines to prevent turnover device, has solved the problem of internal stress, avoids the ap
