Advantages

Excellent Electrical Insulation Performance

High-quality tempered glass features stable dielectric strength and excellent arc resistance, effectively isolating high-voltage conductors and ensuring safe and reliable operation of transmission lines.

High Mechanical Strength & Reliability

Tempered glass body paired with hot-dip galvanized steel fittings provides outstanding tensile and load-bearing strength, stably withstands conductor tension and mechanical stress, with high reliability under long-term service.

Superior Weather Resistance & Self-cleaning Property

The dense and smooth glass surface has good self-cleaning effect and is not easy to accumulate dust; it also features excellent UV resistance, aging resistance and corrosion resistance, adapting to various complex outdoor environments.

Flexible Installation & Easy Maintenance

Standard cap-and-pin structure supports flexible series assembly to meet different voltage grade requirements; it is convenient for installation and replacement, effectively reducing line operation and maintenance costs.
