description: In this paper, the properties of the corona-suppressing coating of the stator winding insulation, designed to prevent slot discharge and vibration arc drawing were explored. For a long time, a low-resistance conductive coating has been used for this purpose. Due to higher operating temperatures of high-voltage machines, the effectiveness of this coating decreases; it is necessary to study the reasons for this phenomenon when the corona-suppressing coating is exposed to high temperatures for a long time. To do this, research of changes in the properties of a low-resistance coating exposed to high temperatures was carried out. Various ways of improving the coating manufacturing method were considered: the standard version, additional mixing and preliminary drying of the filler. Results of this work: 1. An experimental assessment of the resistance of conductive coatings to high temperatures was carried out. 2. The dependences of the performance degradation depending on the temperature and the coating production method were obtained. 3. Possible ways of solving the problem were suggested.
