    摘要: A method of restoring electrical distribution cafes that have lowered performance due to treeing is carried out by (i) supplying the interstices of stranded aluminum conductor portions of such cafes with a restoration fluid comprising an alkoxysilane or mixture of alkoxysilanes selected from aromatic functional alkoxysilanes, alkylalkoxysilanes, amino functional alkoxysilanes, epoxy functional alkoxysilanes, fluoro functional alkoxysilanes, vinyl functional alkoxysilanes, or methacrylate functional alkoxysilanes; and (ii) adding a sulfidosilane, a mercapto functional alkoxysilane, a phosphonated silane, or mixtures thereof, to the restoration fluid to improve the corrosion resistance of the aluminum, as it comes into contact with corrosive agents at elevated temperatures.
