Method for enhancing the dielectrical strength of cable using a fluid mixture

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> cm<2>/second at 50 DEG C. in the insulation of the cable and the mixture has an initial viscosity of
