ABSTRACT:
Method and apparatus for replacing a portion of the insulating sheath of a submarine electric cable when the ends are inaccessible in which a split extrusion mold is placed around the cable and secured to the head of an extruder which is mounted on a carriage movable axially of the cable. The cable is held in a fixed position and as new insulating material is injected into the mold and extruded over the portion of the cable from which the old insulation has been removed, the carriage is moved at a rate dependent upon the extrusion rate. The interior of the mold may be subjected to vacuum. Alternatively, the mold may be held stationary and the cable moved axially thereof.
