Why Glass Insulators Still Shine in Modern Grids
Glass insulators have been a cornerstone of power transmission for over a century, and for good reason. Unlike other materials, glass offers unique advantages:
- Visibility: Cracks or defects are easily spotted, enabling proactive maintenance.
- Weather Resistance: Impervious to UV radiation, moisture, and temperature extremes.
- Longevity: Minimal degradation over decades, even in polluted or coastal environments.
While polymer and ceramic insulators dominate certain niches, glass remains unmatched for applications requiring transparency, durability, and low maintenance.
