1.Key Characteristics of U70BS glass insulator:
Material: Made from toughened or tempered glass.
Shape: Typically a disk or bell shape, part of a string insulator assembly.
Strength: Designed to handle mechanical loads, such as those caused by wind or ice, as well as the electrical load of high-voltage lines.
Voltage Rating: Suitable for medium to high voltage applications.
Usage: Commonly used in overhead power lines to insulate conductors and keep them separated from the support structures.


2.Advantages of U70BS glass insulator :
High Durability: Resistant to UV radiation, aging, and weathering.
Self-Cleaning: Due to the smooth surface, they shed contaminants like dust and dirt, reducing the risk of flashover.
Transparency: Easier to inspect for damage or defects since internal cracks and flaws are more visible compared to other materials like ceramic.
