Description :

　　 Anti pollution glass insulator U70BP/146 specification aluminum conductor steel reinforced (ACSR)

　　Characteristics of glass insulators:

　　 Glass insulators are divided into: standard type, pollution resistant type, DC type, spherical type, air knife type, ground wire type, and are used for the overhead contact system of electrified railways.

　　This product is used for insulation and suspension of conductors in high-voltage and extra local voltage AC/DC transmission lines. The product has an iron capComposed of steel feet and bonded together with cement adhesive. This product adopts all international cylindrical head structures, characterized by a small head size. Lightweight, high strength, and large creepage distance. To meet the needs of live working, traditional domestic structural shapes are used on the brim of the hat. Zero value self breaking, easy to detect Tempered glass insulators have the characteristic of self breaking. 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 annual operating rate is 0.02-0.04%, which can save maintenance costs of the line. Good resistance to arc and vibration, the new surface of the glass insulator subjected to lightning burns during operation is still a smooth glass body with a tempered internal stress protection layer. Therefore, it still maintains sufficient insulation and mechanical strength.

　　 There have been multiple incidents of conductor icing causing vibration on the 50Okv transmission line. After testing, the mechanical and electrical performance of the glass insulator affected by conductor vibration did not deteriorate. Good self-cleaning performance and resistance to aging. According 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 have been conducted. Accumulating thousands of data points, it has been shown that the mechanical and electrical performance of glass insulators after 35 years of operation is consistent with their factory base, and there is no aging phenomenon. Large main capacity, uniform voltage distribution in series The dielectric constant of glass is 7-8, and the extended glass has a large main capacitance and uniform voltage distribution in series, which is conducive to reducing the voltage borne by insulators near the wire side and ground side, thereby reducing radio interference, reducing corona losses, and extending the life of glass insulators. This has been proven in practical operation.

　　High voltage line insulators

　　High voltage line rigid insulators: including needle type porcelain insulators, porcelain cross arm insulators, and butterfly type porcelain insulators. High voltage line porcelain cross arm insulators can be divided into four types according to their structural forms: all ceramic, adhesive, single arm, and V-shaped; According to the installation form, it can be divided into two types: upright and horizontal; According to the 50% full wave impulse flashover voltage, it can be divided into levels such as 185kV, 21OkV, 280kV, 380kV, 450kV, and 610kV. Used for high-voltage overhead transmission and distribution lines, it can replace pin and suspension insulators and eliminate the need for high pole porcelain supports.

　　 Insulators are generally made of glass and porcelain. It is mainly used to fix wires to electrical poles and insulate wires from electrical poles. Insulators are one of the key components of high-voltage transmission lines, and their performance directly affects the operational safety of the entire transmission line. Glass insulators are widely used due to their zero value self breaking and easy maintenance characteristics.

　　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.
