Recycled Glass Insulator Factory

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

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 after several years of operation.

Glass insulators can 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 maintenance. When the 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 off. The self-breakage rate of glass insulators is a crucial quality indicator for product quality and also serves as a quality criterion for bidding and tendering in transmission engineering projects.
