摘要:
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·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.
