Definitions
- the predetermined maximum ratio of interstitial cable volume to volume of dielectric enhancement fluid required for a desired predetermined level of treatment is preferably no greater than 2.0, still more preferably no greater than 1.6, even more preferably is greater no than 1.4, and most preferably, is within a range of 1.3 to 1.4.
- the present invention thus provides a method of utilizing diluents to enhance the performance of dielectric enhancement treatment where there is a danger of supersaturation, particularly, in large diameter cables.
