| Summary: | Rejuvenation technique on cable insulation failures is a hot topic in improving production benefits for electric related enterprises. Breaking the traditional thought of repair action without extensive former damage in scale of the cable insulation, the proposed technique starts from the local standard geometry elimination on insulation or sheaths around cable insulation failure section(s). And then, one standard injection molding technique is applied for rejuvenation on eliminated insulation no matter of the failure resulting from water tree or local mechanical damage or other modes. By this advancement, an injection molding technique is perfectly developed for rejuvenation on cable insulation failure. Frame work on this technigue is hear introduced and it consists of three branches including injection molding material development, standard injection plastic molding technique, and coded quality approval regularities. Realizability and reliability of the present technigue have been verified by sampling testing to expect to be wide applied in production.
