Creation of Hydrophilic Organosilicon Coatings and Study of Their Resistance to Factors Accompanying Corona Discharge

Modern power industry widely uses high-voltage overhead lines to transport electrical energy, with these lines encountering the problems of corona discharge and leakage currents, especially under the conditions of rain and snowfall. One of the approaches to solving these problems is the creation of protective coatings that can diminish corona discharge under adverse weather conditions. This paper reports the results of studying a hydrophilic organosilicon coating based on aminopropyltriethoxysilane and poly(ethylene glycol) for aluminum wires. The study of the coating resistance to a long-term contact with water, UV radiation, and ozone-saturated atmosphere has shown that the hydrophilicity of the coating increases under the influence of these factors, thus improving its anticorona properties. Thus, the durability of the developed coating under the operating conditions opens prospects for its use in the power engineering.
