Toughened Glass Insulator

The Glass Insulator is composed of an iron cap, toughened glass parts and steel pin, which are combined with cement adhesive. Before assembling, the top of the steel pin is provided with a soft gasket, the inner cavity of the iron cap and the pin ends at the contact point with the cement adhesive are covered by tar. The gasket and tar are used to buff in case of damage when insulator facing thermal expansion and contraction. Toughened glass parts are used to insulate.

Characteristics of glass insulators

Small size, light weight, zero-value self-breaking, and easy detection; high mechanical strength; good arc resistance; good self-cleaning performance and not easy to age. In addition, the spraying material has the advantages of strong hydrophobicity, long-term resistance to pollution, low leakage current on the surface, and maintenance-free during operation; it is widely used in various circuits at home and abroad.
