The present invention discloses a manufacturing process for a termination injection molding stress control module for cross-linked polyethylene insulated cable body, which comprises the steps of melting and cross-linking a cable factory insulation layer and a filling insulation; melting and cross-linking the cable factory semiconducting layer and a filling semiconducting layer; and melting and cross-linking the filling insulation and the filling semiconducting layer. The manufacturing process is convenient to operate, and the manufactured stress control module is integrated with the cable body; the electrical property of electric field stress distribution is stable, the problem that an active interface is generated between the cable and the stress control module as they are made of different materials is solved, and the problem of breakdown of cable insulation as a result of local electric field distortion of the insulating layer caused by space charge accumulation at an insulation border is avoided. The manufacturing process of the present invention breaks through the technical bottleneck in the industry worldwide that an ultra-high voltage DC cable is free of termination connection, and meets the requirements for submarine cable as well as AC and DC high-voltage/ultra-high-voltage cable termination on-site manufacture and breakdown rescue.
