High Mechanical Strength
Toughened glass insulators offer superior mechanical performance with rated mechanical loads ranging from 40kN to 300kN. Their strength ensures reliable performance under extreme tension in high-voltage transmission lines, making them ideal for both long-span and heavy-load applications.
Excellent Electrical Insulation
With high dielectric strength, glass insulators effectively prevent current leakage and flashovers even under polluted or humid conditions. Their transparency allows easy detection of internal defects or cracks during inspection, improving maintenance efficiency.
Anti-Aging and Long Service Life
The tempered glass surface resists aging, UV degradation, and environmental stress. Unlike porcelain insulators, glass does not degrade in mechanical strength over time, ensuring consistent performance for decades.
Self-Cleaning Properties
The smooth glass surface reduces the adhesion of dirt, salt, and industrial pollution. Natural rain and wind help wash away contaminants, minimizing the risk of flashovers in coastal, desert, or high-pollution areas.
Safety Breakage Design
In case of damage, toughened glass shatters into small, blunt pieces without sharp edges, preventing injury and avoiding dangerous falling debris in overhead line operations.
Corrosion and Weather Resistance
Glass is highly resistant to temperature changes, moisture, and chemical attack, making it suitable for a wide range of climates—from humid tropical regions to cold and dry environments.
