Abstract
Resinous compositions used as electric insulation have unique corona-resistance increased from 10- to 100-fold or more by the addition of organoaluminate, organosilicate or fine alumina or silica of critical particle size, and dynamoelectric machines and transformers incorporating coils made of wire strands coated with these novel compositions consequently have substantially increased service lives.
