What Is High Voltage Glass Insulators？

glass insulators are commonly used on high voltage power lines to provide electrical insulation and mechanical support for the conductors. they are made of tempered glass and are typically used on voltage lines up to 33 kv.

some key characteristics of glass insulators include:

• high dielectric and mechanical strength to withstand high voltages and conductor loading
• resistance to contamination, though they can be impacted by dust and pollutants in some environments
• thermal stability and low thermal expansion coefficient, making them resistant to temperature variations
• electrical resistance of around 500-1000 kv per centimeter
• visibility of cracks or faults due to the crystalline nature of glass

composite insulators and polymer insulators have become more popular in some applications due to their lighter weight and improved performance in certain conditions. while glass insulators are still commonly used, utilities and manufacturers often recommend ceramic and polymer insulators for high voltage transmission lines. the choice depends on factors like voltage level, environmental conditions, and specific application requirements. if you are not clear which type you need, pls contact us for help - hunan nooa electric co., ltd. - your high voltage insulators expert on power lines.
