Recycled Glass Insulator Manufacturer

Glass insulators, in the first few 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 glass generally remains constant throughout its operation, and its aging process is much slower than porcelain. Therefore, glass insulators are mainly retired due to self-damage, which occurs within the first year of operation, whereas defects in porcelain insulators are only discovered years later.

Glass insulators eliminate the need for regular preventive tests on the insulators during operation, as any damage to the tempered glass will cause the insulator to fail, making it easily detectable during routine inspections. When an insulator is damaged, glass fragments near the steel cap and iron foot get trapped, and the remaining mechanical strength of the insulator is sufficient to prevent the insulator string from breaking. The self-breakage rate of glass insulators is a critical indicator of product quality and serves as a quality basis for bidding and tendering in transmission projects.
