Abstract
A dielectric enhancement fluid composition having at least one organoalkoxysilane and an acid catalyst having a pKA less than about 2.1 and a method for using the composition to enhance the dielectric properties of an electrical cable having a central stranded conductor encased in a polymeric insulation and having an interstitial void volume in the region of the conductor, the method comprising at least partially filling the interstitial void volume of the cable with the composition. The fluid composition may further include an organometallic catalyst and a corrosion inhibitor.
Claims40
A method for enhancing the dielectric properties of an electrical cable having a central stranded conductor encased in a polymeric insulation and having an interstitial void volume in the region of the conductor, the method comprising at least partially filling the interstitial void volume with a dielectric enhancement fluid composition comprising
- (a) at least one organoalkoxysilane;
- and
- (b) an acid catalyst having a pKA less than about 2.1.
A method for enhancing the dielectric properties of an electrical cable segment having a central stranded conductor encased in a polymeric insulation jacket and having an interstitial void volume in the region of the conductor, the method comprising:
- (i) substantially filling the interstitial void volume with at least one dielectric property-enhancing fluid composition at a pressure below the elastic limit of the polymeric insulation jacket;
- and
- (ii) confining the dielectric property-enhancing fluid composition within the interstitial void volume at a residual pressure greater than about 50 psig, the pressure being imposed along the entire length of the section and being below the elastic limit, wherein the composition comprises:
- (a) at least one organoalkoxysilane;
- and
- (b) an acid catalyst having a pKA less than about 2.1
A dielectric enhancement fluid composition for enhancing the dielectric properties of an electrical cable having a central stranded conductor encased in a polymeric insulation and having an interstitial void volume in the region of the conductor by at least partially filling the interstitial void volume, the dielectric enhancement fluid composition comprising:
- (a) at least one organoalkoxysilane;
- and
- (b) an acid catalyst having a pKA less than about 2.1.
