  • Disk type suspended glass insulators are used for insulation and fixing wires in high-voltage overhead transmission and distribution lines;
  • Generally assembled into insulator strings for use on lines of different voltage levels;
  • Ordinary insulators are suitable for general areas;
  • Appropriately increasing the number of insulator pieces can improve the pollution flashover performance.
