Patent ID: 8476528

Claim:
A method of fabricating an electrical conductor having an insulating coating, the method including the steps of: providing the electrical conductor; coating the electrical conductor with at least one layer of a flexible insulating percursor material on the electrical conductor, the percursor material comprising: a first organo-alkoxide 1 R x Si(O 1 R′) 4-x , a second organo-alkoxide 2 R x Si(O 2 Ry x and an inorganic filler material, where 1 R is a non-hydrolysable organic moiety thermally stable to a temperature of at least 150° C., 2 R is a non-hydrolysable organic moiety containing a functional group that can react with another like functional group to form an organic polymer 1 , wherein R′ and 2 R′ are alkyl radicals and x is 1 or 2.
