High Voltage 100 kN Toughened Glass Insulator U100CN
Comprehensive Guide to Earth Wire Disc Suspension Glass Insulators
Structural Composition of Glass Insulators
Earth wire disc suspension glass insulators are designed with insulated parts made from high-quality materials such as tempered glass, ceramics, or silicone rubber. These materials are renowned for their excellent insulation performance, capable of withstanding high voltage and preventing current leakage to the ground.
- Insulated Parts: The tempered glass insulators have unique characteristics like zero value self-rupture, making detection easy. Even after a lightning strike, the surface remains smooth, retaining sufficient insulation performance and mechanical strength.
- Connection Fittings: Essential for connecting insulators together, forming insulator strings, and attaching them to towers and wires. Typically, hot-dip galvanized iron caps and steel feet are used to prevent rust and corrosion, ensuring durability and reliability.
- Locking Pins: The spherical connection structure features push-pull elastic locking pins in W-type and R-type forms, constructed from copper for excellent elasticity and corrosion resistance.

Working Principle
The primary function of earth wire disc suspension glass insulators is to maintain insulation between the ground wire and the tower. They help prevent current leakage, ensuring the normal operation of power systems while handling both electrical and mechanical stresses during line operation.
Pollution Resistance
In areas prone to pollution, these insulators enhance insulation performance by increasing the creepage distance and employing special umbrella-shaped structures to prevent pollution flashover accidents. This design offers a low dust accumulation rate and excellent self-cleaning performance in wind and rain.
