Glass insulator Glass insulator manufacturers on product structure analysis; The product consists of an iron cover, tempered glass sheets and steel feet, which are bonded together by cement. All products use the world's advanced cylindrical head structure, which is characterized by small head size. Light weight, high strength, large creepage distance. It can save metal materials and reduce line costs. In order to meet the needs of the field work, the brim of the hat adopts a traditional home structure. Yunhang zero value self-breaking, easy to detect. The tempered glass insulator has the characteristic of zero value self-breaking. As long as it can be observed on the ground or in a helicopter, there is no need to climb the pole piece by piece for inspection, reducing the labor intensity of workers. The self-breaking rate of imported products in the production line is 0.02-0.04% per year, which can save the maintenance cost of the production line. Good arc resistance and vibration resistance. The new surface of the glass insulator that suffered lightning damage during operation is still a smooth glass body with a tempered internal stress protection layer.
