Abstract

Composition and method for enhancing the dielectric strength of an in-service solid dielectric shielded electrical cable and preventing corrosion of a central aluminum conductor of the cable by supplying the cable with an alkoxysilane composition. In one embodiment, the alkoxysilane composition includes dimethyldi(n-butoxy)silane.

Claims (22)

1. A method for enhancing the dielectric strength of an in-service solid dielectric shielded electrical cable and preventing corrosion of an aluminum central conductor encased in an insulation jacket and having an interstitial void volume in the region of the conductor, comprising:

supplying the interstitial void volume with an alkoxysilane composition comprising a dialkoxysilane having the formula:

(R 1 O)(R 2 O)SiR 3 R 4

wherein R 1 and R 2 are independently selected from the group consisting of C 4 and C 5 alkyl groups; and

wherein R 3 and R 4 are independently selected from the group consisting of C 1 alkyl, C 2 alkyl, and C 3 alkyl.

2. The method of claim 1 , wherein the composition further comprises a hydrolysis catalyst.

3. The method of claim 1 , wherein the composition further comprises a non-functional dye.

4. The method of claim 1 , wherein the C 4 alkyl group is selected from the group consisting of n-butyl, s-butyl, and i-butyl groups.

5. The method of claim 1 , wherein the C 5 alkyl group is selected from the group consisting of n-pentyl, s-pentyl, and i-pentyl groups.

6. The method of claim 1 , wherein R 1 and R 2 are n-butyl groups.

7. The method of claim 1 , wherein R 1 and R 2 are n-pentyl groups.

8. The method of claim 1 , wherein the dialkoxysilane is a dialkyldibutoxysilane.

9. The method of claim 1 , wherein the dialkoxysilane is selected from the group consisting of a dimethyldibutoxysilane, a diethyldibutoxysilane, and a dipropyldibutoxysilane.

10. The method of claim 1 , wherein the dialkoxysilane is dimethyldi(n-butoxy) silane.

11. The method of claim 1 , wherein the dialkoxysilane is a dialkyldipentoxysilane.

12. The method of claim 1 , wherein the dialkoxysilane is selected from the group consisting of a dimethyldipentoxysilane, a diethyldipentoxysilane, and a dipropyldipentoxysilane.

13. The method of claim 1 , wherein the dialkoxysilane is dimethyldi(n-pentoxy) silane.

14. A method for enhancing the dielectric strength of an in-service solid dielectric shielded electrical cable and preventing corrosion of an aluminum central conductor encased in an insulation jacket and having an interstitial void volume in the region of the conductor, comprising supplying the interstitial void volume with an alkoxysilane composition comprising a dialkoxysilane selected from the group consisting of a dimethyldibutoxysilane and a dimethyldipentoxysilane.

15. The method of claim 14 , wherein the dialkoxysilane is dimethyldi(n-butoxy) silane.

16. The method of claim 14 , wherein the dialkoxysilane is dimethyldi(n-pentoxy) silane.

17. The method of claim 14 , wherein the composition further comprises a hydrolysis catalyst.

18. The method of claim 14 , wherein the composition further comprises a non-functional dye.
