A power line arrester is an electrical device used to protect power lines and electrical equipment from lightning overvoltage and operating overvoltage.

It is usually installed on power line towers or in substations.

When the line is struck by lightning or an operating overvoltage occurs, the arrester can act quickly to limit the overvoltage to a certain range, thereby protecting the insulation of the line and equipment and ensuring the safe and stable operation of the power system.

 

Functions:
* Electrical Insulation: It insulates the transformer windings' outgoing connections from each other and from the transformer bushing, preventing current leakage and short-circuit faults.
* Mechanical Support: It securely fixes the outgoing connections, ensuring they remain stable and properly positioned during operation.

Performance Features
--Good protection performance: It can respond to overvoltage quickly, limit the overvoltage amplitude to a low level, effectively protect the insulation of power equipment, and reduce the risk of equipment damage due to overvoltage. --High reliability: It adopts advanced manufacturing technology and high-quality materials, has good stability and aging resistance, and can maintain reliable working condition in long-term operation. --Maintenance-free: The arrester does not require special maintenance under normal operating conditions, reducing the operation and maintenance costs and workload.
