Abstract:
1. A method for extending the useful life of at least one in-service electrical cable section having a stranded conductor surrounded by a conductor shield encased in a polymeric insulation and having an interstitial void volume in the region of the conductor, the cable section having an average operating temperature T, the method comprising: injecting a dielectric enhancement fluid composition into the interstitial void volume, the composition comprising at least one component selected from (1) a water-reactive material selected from: (2) a water-reactive material selected from (3) a non-water-reactive organic material which has a diffusion coefficient of less than about 10 (4) an organic compound having an equilibrium concentration in the polymeric insulation at 55° C. which is less than 2.25 times the equilibrium concentration at 22° C.
