The product is composed of iron cap, toughened glass piece and steel foot, and is cemented as a whole.This product adopts the most advanced cylindrical head structure in the world, which is characterized by small head size.Light weight, high strength and high creepage distance.It can save metal material and reduce line cost.In order to meet the need of live work, the traditional structure shape is adopted on the cap brim.
The tempered glass insulator has the characteristic of zero self - breaking.As long as the observation on the ground or in the helicopter, there is no need to mount the pole piece by piece detection, reduce the labor intensity of workers, save the maintenance cost of the line.
The new surface on which the glass insulator suffers lightning burns during operation is still a smooth vitreous body and has a tempered internal stress protection layer, so that it can retain enough energy and mechanical strength of the insulating part.
The dancing hazard caused by the ice tread of the conductor occurred many times on the 500kV line. After the dancing of the conductor, the glass insulator was tested, and the mechanical and electrical performance did not decay.
It is generally reported by the power sector that glass insulators are not easy to accumulate dirt and easy to clean, and the glass insulators running on the southern line are washed clean after rain.The mechanical and electrical properties of glass insulators in typical areas are measured by regular sampling. Thousands of data have been accumulated to show that the mechanical and electrical properties of glass insulators after 35 years of operation are basically the same as those when they left the factory, and there is no aging phenomenon.
