Glass Insulator

Since 1958, the total sales volume of Thunder Lightning brand tempered glass insulator has exceeded 100 million pieces, accounting for half of the country and one sixth of the world. 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. Glass insulators have the characteristics of 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. Disk suspension glass insulators are divided into standard type, anti-pollution type, DC type, , aerodynamic type, out-ribs type and ground wire type.
