High voltage suspension 70 kN electrical porcelain insulator U70B porcelain insulators

70kN standard disc suspension porcelain insulator U70B 70kN standard disc suspension porcelain insulator U70B is a very common and popular porcelain insulator in Chinese market and overseas market such as Bangladesh, Vietnam, Iran, Algeria etc. Jiangxi huayao electric Co.,ltd is professional in produce this item, the daily output of this item is 10000 pieces.

Cap insulator: The insulation part is circular or cap shaped, which is commonly used in scenarios such as equipment connection in power systems and can provide good insulation protection.
Disc insulator: It has a disc-shaped insulating part and is widely used in high-voltage equipment. The disc-shaped suspension ceramic insulator, with its disc-shaped structure, helps to increase the creepage distance and improve insulation performance.
String insulator: composed of multiple insulator units connected in series. By connecting multiple insulators in series, the electrical insulation strength can be improved to meet the insulation requirements of high-voltage lines.
