The main advantages of glass insulators
2025-06-18
Zero-value self-breaking characteristic: Glass insulators have a 'zero-value self-breaking' self-elimination capability. When defects occur in the glass body, it will automatically break, which is convenient for detection and replacement. After self-breaking, the iron cap residual hammer still maintains mechanical strength to hang on the line, which does not affect the line operation, and the line patrol personnel can find and replace it in time.
Easy to detect: Due to the transparency of glass, it is easy to find small cracks and various internal defects and damages during visual inspection, without the need to climb the tower for piece-by-piece inspection, which saves a lot of manpower and material resources.
Stable performance: The surface of glass insulators has high mechanical strength, the surface is not easy to crack, the aging speed is slow, and the electrical performance is higher than that of porcelain insulators. Operating practice shows that the electromechanical performance of glass insulators after 35 years of operation is basically the same as when they left the factory, and no aging phenomenon has occurred.
Light weight and high strength: The electromechanical performance of tempered glass is much higher than that of porcelain. To manufacture the same type of insulator, the size and weight of glass insulators are much smaller than those of porcelain insulators, and they also have higher mechanical strength.
Large main capacitance and uniform voltage distribution: The dielectric constant of glass is 7 - 8, which makes tempered glass insulators have a large main capacitance and uniform voltage distribution in strings, which is beneficial to reduce the voltage borne by insulators near the conductor side and the ground side, reduce radio interference, reduce corona loss and extend the life of glass insulators.
High production efficiency: Fewer production steps, short production cycle, and easy mechanization and automation of production.
