Abstract
An impregnating material used for insulating the windings of a dynamo-electric machine is prepared by the hydrolysis of a solution of ethyl-silicate by a strong mineral acid and a dilute aliphatic alcohol and filled by an inorganic filler. Preferably, the solution comprises by volume 4 parts of aliphatic alcohol and 1 part of 0.5-1% phosphoric or hydrochloric acid per 5 parts of ethyl-silicate, to which after blending, 5 parts of alcohol and 2-10 parts by weight of an inorganic pulverized filler are added.ALSO:A solution of a dressed gel of silicic acid is used to impregnate the insulation of a dynamo-electric machine. The insulation comprises glass and mica slot insulation and glass braiding and tape winding insulation bonded by a silicon varnish which is driven off when the assembly is repeatedly heated to between 300 DEG C. and 500 DEG C. initially (100-500 DEG C. subsequently) before cooling and impregnating. The solution is prepared by the hydrolysis of a solution of ethyl-silicate by a strong mineral acid and a dilute aliphatic alcohol with an inorganic filler material added. Preferably the solution comprises by volume, 4 parts of aliphatic alcohol and 1 part of 0.5% phosphoric or hydrochloric acid per 5 parts of ethyl-silicate, to which after blending, 5 parts of alcohol and 2-10 parts dry weight of an inorganic pulverized filler are added.
