Mould and process are developed for an injection molding rejuvenation technique of cable insulation failure. Disregard the traditional clue that repair does not expand original damage in size and space, a new rejuvenation technique, i.e. injection molding, is developed for restoring cable insulation failure. In this technique the uncertain damage in size and space was replaced by a standard eliminated size and space. In this way, an expanded original damage with certain size and space is firstly made around cable insulation failure section. But the damage situation was modified to a standard mode so that a mould technology can be well applied to filling the modified size and space. In addition, the bigger size and space is applied by mould for over-filling the modified size and space. Then a standard process should be constructed by the repair practices till the quality testing verifies that a successful rejuvenation is reached. Applied practice has verified the applicability and availability of the present technique.
