Protective fittings: arcing rings, arcing horns, grading rings
Protective fittings for insulator strings: lower one- and two-electrode arcing rings, upper, middle and two-sided arcing horns, horns for composite insulators, and upper and lower grading (corona) rings — they divert the flashover arc away from the insulator
- Material

Description
Protective fittings for insulator strings: lower one- and two-electrode arcing rings, upper, middle and two-sided arcing horns, horns for composite insulators, and upper and lower grading (corona) rings — they divert the flashover arc away from the insulator and even out voltage distribution along the string.
Specifications: Material — hot-dip galvanised steel; Voltage — 110, 220 and 400 kV; Short-circuit current — 25–40 kA (arcing rings 31.5–40 kA, horns for composite insulators 25 kA, grading rings 40 kA).
Applications: 110–400 kV lines: long-rod and composite insulator strings.
