100 kN Toughened Glass Insulator U100C

Structural Composition of Earth Wire Disc Suspension Glass Insulator

The earth wire disc suspension glass insulator is composed of insulated parts and connection fittings. Insulated parts are typically made from durable materials like glass, ceramics, or silicone rubber, offering excellent insulation capabilities and resistance to high voltage and current leakage. Tempered glass insulators have self-rupture characteristics that are easy to detect, maintaining insulation performance even after lightning burns.

Connection Fittings

The insulators are connected using hot-dip galvanized iron caps and steel feet to ensure rust and corrosion resistance while maintaining a strong connection. The push-pull elastic locking pin, available in W-type and R-type made from copper, provides good elasticity and corrosion resistance.
