Disc-shaped suspension glass insulators use toughened glass as the core insulating material, with a shape and installation method similar to disc-shaped porcelain insulators, allowing multiple strings to be combined to suspend conductors. The glass material is inherently transparent, enabling line patrol personnel to visually inspect internal micro-damage with the naked eye, reducing fault detection difficulty. The toughened glass structure offers stable mechanical strength, performing well against outdoor impacts and hail strikes. Rainwater naturally washes away surface contaminants, providing better self-cleaning than some ceramic products and reducing the frequency of offline inspection and cleaning. Suitable for high-voltage and extra-high-voltage long-distance transmission lines, they can be deployed in mountainous and coastal humid areas. As a modern traditional insulating component, it balances mechanical performance and maintenance advantages, gradually being adopted in new long-distance transmission lines.
