Study on Characteristics of Surface Discharge of Silicone Rubber under High-speed Airflow

High-speed train roof insulators are the key equipment for train high-voltage isolation and pantograph mechanical support. Their good insulation performance is the basic condition to ensure the safe operation of trains. With the rapid development of high-speed trains, the speed of trains is getting faster and faster. The silicone rubber insulators on the train roofs are exposed to the atmospheric ...
