U70B/127 specification high-voltage suspension glass insulator photovoltaic cable

Description :

　　 U70B/127 specification high-voltage suspension glass insulator Photovoltaic cable

　　Characteristics and Applications of Insulators:

　　The products include:Standard stain resistant type DC type spherical type aerodynamic type ground wire type electrified railway contact system.

　　 The product is used for insulation and suspension of conductors in high-voltage and ultra high voltage AC/DC transmission lines. The product consists of iron caps, tempered glass components, and steel anode groups

　　This shared water is now combined and glued together as a whole. This product adopts the international cylindrical head structure, which is characterized by a small head size.

　　Lightweight, high strength, and large creepage distance.

　　Can save metal materials and reduce line costs. To meet the needs of live working, on the edge

　　Using traditional domestic structural shapes. The tempered glass insulator has the characteristic of zero value self breaking, which is easy to detect. As long as it's on the ground or straight

　　Observation on the elevator is sufficient, without the need to climb the pole and inspect each piece, reducing the labor intensity of workers. The annual self destruct rate during operation is 0.02-0.04%, which can be saved

　　The maintenance cost of the line. The glass insulator has good resistance to arc and vibration, and the new surface of the glass insulator that has been burned by lightning during operation is still a smooth glass body

　　And it has a tempered internal stress protection layer, so it still maintains sufficient insulation and mechanical strength.

　　 There have been multiple incidents of conductor icing causing vibration on 500kV transmission lines. After testing, the mechanical and electrical performance of the glass insulators affected by conductor vibration was found to be poor

　　There is attenuation. 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, and the southern power lines are in operation

　　The glass insulator is washed clean after rain. Regularly sample and measure 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 when they were manufactured, and there is no aging phenomenon. Main content

　　Large quantity, uniform voltage distribution in series. The dielectric constant of glass is 7-8, which makes the glass insulator have 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 grounding side, thereby reducing radio interference, reducing electrical losses, and blue interference

　　The purpose of the lifespan of long wave Yunnan insulators has been proven through operational practice.

　　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.
