product description
Ordinary insulators are suitable for general areas. Properly increasing the number of insulators can also improve the pollution flashover performance. Disc suspension porcelain insulator is a special insulation control, which can play an important role in overhead transmission lines.
High voltage line pollution resistant disc-shaped suspension porcelain insulator is suitable for industrial dust, chemical industry, saline alkali, coastal and foggy areas. It is used for insulation and fixed conductors on high-voltage overhead transmission and distribution lines. It is generally assembled into insulator strings for power lines in different voltage levels and different pollution areas.
