20 Claims

1. A method for rejuvenating a strand-blocked cable having a conductor comprised of a plurality of conductor strands with interstitial volume therebetween blocked by a PIB based mastic, the conductor being surrounded by a polymeric cable insulation, comprising:

installing injection adapters that seal the cable ends of the cable and are usable to inject fluid into the interstitial volume between the conductor strands of the cable;

elastically expanding the polymeric cable insulation through the application of pressure to the interstitial volume between the conductor strands of the cable;

injecting at least one injection fluid in which the PIB based mastic is at least partially soluble into the interstitial volume between the conductor strands of the cable; and

flushing the at least one injection fluid through the interstitial volume of the conductor strands to create at least 10% more interstitial volume by removing PIB based mastic.
