Quick Detail: 

Glass Disc Insulator For 70kN High Voltage Glass Suspension insulator


Insulators are commonly used as a flexible coating on electric wire and cable. Since air is an insulator, in principle no other substance is needed to keep power where it should be. High-voltage power lines commonly use just air, since a solid (e.g., plastic) coating is impractical. However, wires which touch each other will produce cross connections, short circuits, and fire hazards. In coaxial cable the center conductor must be supported exactly in the middle of the hollow shield in order to prevent EM wave reflections. Finally, wires which expose voltages higher than 60V can cause human shock and electrocution hazards. Insulating coatings help to prevent all of these problems.

Product features
♦ 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.
♦ 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. When the insulator is damaged, glass fragments near the steel cap and iron foot get stuck, and the remaining part of the insulator is strong enough to prevent the string from breaking off. The slope ratio of glass insulator is one of the important indexes to measure the product quality, and it is also the quality basis of the current power transmission project bidding.
♦ 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 maintenanc.
Insulator is a special insulating control which can play an important role in overhead transmission line. In the early years, insulators were mostly used in power poles. Gradually, they developed into a kind of dial-shaped insulator hanging at one end of the high type high-voltage wire connecting tower. The purpose of insulators is to increase the creepage distance. Insulators should not fail due to various electromechanical stresses caused by changes in the environment and electrical load conditions. Otherwise, insulators will not play a significant role and will damage the service life of the entire line.
