摘要

In-service PIC telephone cable that has become water-logged in places is reclaimed dielectrically by pumping in an aromatic solvent oil containing cross-linking agents that will gel the oil in a predetermined period preferably of the order 24 hours. A nongelling prepurgent miscible with both water and aromatic solvent oil may be pumped in before the gelling compound is introduced, to more completely purge the water.
