CONNECTING METHOD FOR SUBMARINE CABLE

PROBLEM TO BE SOLVED: To provide a submarine cable connecting method which enables formation of an external conductor layer having sufficient adaptability. SOLUTION: In stepped stripping of submarine cables 1, 1', a plurality of strands 6a, 6b are cut and removed at a position, where forming of an insulation reinforcing layer 11 to the periphery of the joint of their internal conductors 2, 2' becomes feasible, and an insulation reinforcing layer 11 is formed in the removed part. First welded parts 19 are formed by welding the end surfaces of the strands 5a, 5b to the end surface of strands for external conductors, having the same diameters as the end surfaces of the strands 5a, 5b, and are wound on the reinforcing layer 11. Winding is performed in the same directions as the winding of the strands 5a, 5b on external insulators 4, 4', the tip parts of the strands 17, 17 are welded, and second welded parts 20 are formed. The first parts 19 and the second parts 20 are arranged with their positions being shifted on the peripheries of the internal insulators 4, 4' and reinforcing layer 11 respectively, to form an external conductor layer 21 as the result.
