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.
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.
Jiangxi QOCI Electric Co.,Ltd.has been specialized in research and development of latest high-strength functional glass and power transmission insulators,which is the qualified supplier for State Grid Corporation of China and Southern State Grid Corporation of China,and is a participating unit of product standard formulation of the National Insulator Standard Committee.
