Description

Technical Field

This type of lightning arrester adopts a rear-insertion installation method, which can be easily installed and disassembled, and is easy to maintain and replace. It is mainly composed of metal oxides or other nonlinear resistors. When lightning overvoltage or operating overvoltage occurs, these resistors will quickly conduct and limit the overvoltage to a lower level, thereby protecting electrical equipment from damage. The use of rounded corners on the contact surface between the outer shielding layer and the insulating layer can reduce the electric field strength between the outer shielding layer and the external plug connection surface, and will not cause air discharge when the product is not installed in place.
