Key Features of Glass Electric Insulators:

• Superior Dielectric Strength: Glass provides excellent electrical insulation, minimizing the risk of current leakage and ensuring safety.

• Durability: Resistant to weathering, UV radiation, and temperature fluctuations, glass insulators maintain their integrity over time.

• Transparency: The clear nature of glass allows for straightforward visual inspections, facilitating maintenance and early detection of potential issues.

lf there is no special instruction, W pin is used for U70B

Advantages Over Other Materials:

• Self-Cleaning Properties: The smooth surface of glass reduces the accumulation of dirt and pollutants, decreasing maintenance requirements.

• Mechanical Strength: Engineered to withstand mechanical stresses, glass insulators are suitable for various environmental conditions.

• Environmental Impact: Glass is recyclable, making it an eco-friendly choice for sustainable infrastructure projects.
