        Abstract: On the basis of the technology of water tree aging cable rejuvenation based on siloxane, this paper put forward a new solution to solve the aging problem of the distribution network cable. Introduction was made to the water tree aging crosslinked polyethylene cable rejuvenation technology. This paper analyzed the lifting effect of cable insulation performance in practical application and the correlation detection means injecting technology. In practical case the onsite rejuvenation test result of operation cable shows that after the rejuvenation, the aging cable insulation performance is improved significantly, which illustrate the rejuvenation technology plays a good part in recovering the aging cable insulation performance.
        Key words: crosslinked polyethylene cable cables; water-tree age; siloxane; rejuvenation technology
