　　Introduction to the characteristics of tempered glass insulators:

　　 Tempered glass bead (English name: Tempered glass bead), tempered glass insulator products are used for high voltage and ultra-high voltage ACDC transmission lineUsed for insulation and suspension wires. In the early years, tempered glass insulators were mostly used for utility poles, but gradually developed into many disc-shaped insulators hung at one end of high voltage power line connection towers to increase the creepage distance. They are usually made of glass or ceramic and are called insulators.

　　 Tempered glass insulators have the characteristic of zero value self rupture. As long as it is observed on the ground or in a helicopter, there is no need to climb the pole and inspect each piece, which reduces the labor intensity of workers.The products introduced into the production line have an annual self breakage rate of 0.02-0.04%, which can save maintenance costs on the circuit. Good resistance to arc and vibrationThe new surface of the glass insulator that suffered lightning burns during operation is still a smooth glass body with a tempered internal stress protection layer, so it still maintains sufficient insulation and mechanical strength.There have been multiple incidents of conductor icing induced vibration on 500kV transmission lines. After testing, the mechanical and electrical performance of the glass insulators affected by conductor vibration did not deteriorate.Good self-cleaning performance and resistance to agingAccording to the general feedback from the power department, glass insulators are not easy to accumulate dirt and are easy to clean. The glass insulators used in the southern transmission lines are washed clean after rain.

　　Regular sampling and testing of the mechanical and electrical performance of glass insulators on typical regional power lines after operation. Accumulating thousands of data shows that the mechanical and electrical performance of glass insulators after 35 years of operation is basically the same as that at the time of factory delivery, and there is no aging phenomenon.

　　 The tempered glass insulator has a large main capacity, uniform voltage distribution in series, and a dielectric constant of 7-8 for glass, which makes the tempered glass insulator have a large main capacitance and uniform voltage distribution in series. This is conducive to reducing the voltage borne by the insulator near the wire side and grounding side, thereby reducing radio interference, reducing corona loss, and extending the life of the glass insulator. Practical operation has proven this.Tempered glass insulator type: standard type, pollution resistant type, DC type, spherical type, aerodynamic type, ground wire type, used for electrified railway contact network

　　 Yuanzi is often subjected to the effects of gravity and tension of the conductor, wind force, ice weight, self weight of insulators, conductor vibration, mechanical force of equipment operation, short-circuit electric force, earthquake and other mechanical forces during operation. There are strict requirements for mechanical performance in the relevant standards.

　　 Outdoor insulators require the ability to withstand sudden temperature changes. For example, porcelain insulators require several cycles of cold and heat without cracking.insulating sleeveDue to the passage of current, the temperature rise and allowable short-time current value of its components and insulation parts must comply with the relevant standards.

　　Transportation and precautions:

　　 (1) Composite insulators should have good moisture-proof, anti vibration, anti rust, anti-theft and other protective measures to ensure the safe delivery of composite insulators to the site without damage due to the above reasons.

　　(2) Composite insulators with voltage levels of 330kV and above should be packaged in appropriately sized, rainproof, and rodent proof cylinders, and the end caps at both ends should be firm and reliable.

　　(3) The packaging of composite insulators should have sufficient strength to withstand handling during transportation, on-site storage, and installation.

　　(4) Suitable buffering measures should be installed inside the packaging tube to prevent damage or deformation during transportation and handling. All these materials should have chemical stability and waterproofness, and should not adhere to composite insulators or corrode them during outdoor storage.

　　(5) To ensure the safe arrival of goods at their destination, all packaging boxes should have correct, clear, and secure markings.
