ABSTRACT:
A method for selecting components for a mixture to be injected into an interstitial void volume adjacent to a central stranded conductor of an electrical cable segment having the central conductor encased in a polymeric insulation jacket to enhance the dielectric properties of the cable segment. The method includes selecting an anticipated operating temperature for the cable segment to be used in selecting the components for the mixture to be injected into the interstitial void volume of the cable segment and selecting a minimum desired time period to be used in selecting the compounds for the mixture to be injected during which the dielectric properties of the cable segment are to be enhanced by the mixture. Next, first, second and third components for the mixture are selected to provide the cable segment with a reliable life at the selected operating temperature spanning first, second and third time periods, respectively.
