Description:
The mechanical strength of the surface of the glass insulator is high, so that the surface is not prone to cracks. The electrical strength of the glass generally remains unchanged throughout the operation, and the aging process is much slower than the porcelain insulator.
The use of glass insulation eliminates the periodic periodic preventive test of the insulator during operation. This is because each damage of the tempered glass causes damage to the insulator, which is easily detected by the operator during the inspection.
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 the glass insulators are more stable in their own composition than the raw materials used in the manufacture of electric porcelain, creating good conditions for stabilizing the electrical and mechanical properties of the glass.
The electromechanical performance of tempered glass is much higher than that of porcelain, and its size and weight are much smaller than porcelain insulators.
