Abstract

A corona shielding band having reproducible qualities and allowing only a small increase in dielectric losses in a winding of an insulation of electrical machine is made by impregnating a woven-type support material with an active resin solution containing an inorganic filler with a coating composed of antimony-doped tin oxide and then removing the solvent by a thermal processing to produce the corona shielding band.
