High mechanical strength of the surface layer of the glass porcelain insulators, so that the surface is not easy to crack. The electrical strength of the glass is generally remain unchanged during the entire run, and the aging process is much slower than porcelain, glass insulator scrapped mainly due to the self-damage occurred during the first year of the run, but the porcelain insulators defects only running for a few years after discovery. Glass porcelain insulators, periodic preventive test insulator charged during operation can be canceled. This is the destruction of the damage will be caused because each of the tempered glass insulator, operating personnel in the patrol line can easily find it. When the insulator is damaged, the steel cap and iron near the foot of the glass fragments stuck insulators rest of sufficient mechanical strength to prevent the insulator strings broken off. The raw materials used to manufacture glass porcelain insulators on its own ingredients than the manufacture of electrical porcelain with the raw material is more stable, and create good conditions for the electrical and mechanical characteristics of the glass stability.
