A method for enhancing the dielectric properties of new or in-service electrical cable is disclosed, the method comprising supplying the interstitial void space of the cable's conductor with a fluid mixture comprising (A) an antitreeing agent; and (B) a water-reactive compound, wherein (B) has a diffusion coefficient of at least 1 x 10-7 cm2/second at 50°C. in the insulation of the cable and the mixture has an initial viscosity of <=100 cP (mPa.multidot.s) at 25°C. The instant method provides a more symmetrical distribution of dielectric enhancing fluid in the insulation than prior art approaches and results in a significant reduction in cable treatment time.
