Open Profile Toughened Glass Insulator

The open profile toughened glass insulator provides reliable electrical insulation for overhead power lines, especially in harsh environments. Its flat dielectric design makes it ideal for desert areas, minimizing residue accumulation and allowing for effective self-cleaning through natural airflow from wind and rain.

Suitable for regions with critical industrial or mixed pollution, these insulators are made from tempered glass for excellent mechanical strength and durability. The smooth surface enhances insulation performance, while galvanized metal fittings offer additional corrosion resistance.
