Product Characteristics
- Insulator is one of the key components in high voltage transmission line, its performance directly affects the whole the safety operation of the transmission line. Glass insulators are widely used because of their characteristics of zero self-breaking and easy maintenance.
- 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.
- It is made of toughened glass. Due to the high mechanical strength of the surface layer of glass insulator, cracks are not easy to occur on the surface. The electrical strength of glass remains constant throughout its operation and the aging process is much slower than that of porcelain.
- Insulator is a special insulation control, which can play an important role in overhead transmission lines.
