What are the advantages of transparent glass insulators？

Due to the transparency of glass Insulators, small cracks and various internal defects and damages are easy to find during appearance inspection.
Due to the high mechanical strength of the surface of glass insulators, cracks are not easy to occur on the surface. The electrical strength of glass generally remains unchanged during the entire operation period, and its aging process is much slower than that of porcelain. Therefore, glass insulators are mainly scrapped due to self-damage, which occurs within the first year of operation, but the defects of porcelain insulators are only discovered after several years of operation.

The use of glass insulators can eliminate the regular preventive tests of insulators under power during operation. This is because every damage to Tempered Glass will cause damage to the insulator, and it is easy for operators to find it when patrolling the line. When the insulator is damaged, the glass fragments near the steel cap and the iron foot are stuck, and the mechanical strength of the remaining part of the insulator is sufficient to prevent the insulator string from breaking off.
The raw materials used to make glass insulators are more stable than the raw materials used to make electrical porcelain in terms of their own composition, creating good conditions for stabilizing the electrical and mechanical properties of glass.
The electromechanical properties of tempered glass are much higher than those of porcelain, and the size and weight of the same type of insulators are much smaller than those of porcelain insulators.
