Insulator Manufacturer

Glass insulators, during the initial years of production and operation, have been found to have the following series of advantages over porcelain insulators:

Due to the high mechanical strength of the glass insulator surface, it is less prone to cracking. The electrical strength of the glass remains generally constant throughout its operation, and its aging process is much slower than porcelain. Therefore, glass insulators are primarily retired due to self-destruction, which occurs within the first year of operation, whereas porcelain insulator defects are only discovered years after operation.

Glass insulators eliminate the need for regular preventive tests with live voltage during operation. This is because any damage to the tempered glass will result in the destruction of the insulator, which is easily detectable during routine inspections. When an insulator is damaged, glass fragments are caught near the steel cap and iron foot, and the remaining mechanical strength of the insulator is sufficient to prevent the insulator string from breaking off.
