Product characteristics

Made of toughened glass. Because of the high mechanical strength of the glass insulator surface, it is not easy to crack the surface. The electrical strength of glass generally remains constant throughout the operation period, and the aging process of glass is much slower than that of porcelain.
Using glass insulator, it can cancel the operation process of insulator of charged periodic preventive test. This is due to every damage to tempered glass causes damage to the insulator, which operators can easily find when patrolling the wire.
Insulator is a special insulation control, which can play an important role in overhead transmission lines.
In the early years, insulators were mostly used in poles, and gradually developed into high-voltage wire towers with a number of disc-shaped insulators hanging at one end. They were made of glass or ceramics to increase the creeping distance.
Insulators should not fail due to various mechanical and electrical stresses caused by changes in the environment and electrical load conditions, otherwise insulators will not play a significant role, which will damage the service life of the entire line.
