U70BLA 146/380/365 Glass Insulator
The main purpose of aerodynamic glass insulators is to provide insulation and mechanical support for high-voltage transmission lines.
Their specially designed shape effectively reduces wind resistance and prevents the formation of continuous water films during rainy and windy conditions, thereby improving pollution flashover voltage and wind resistance.
