10kV630A European Separable connector arrester

 

10kV European style rear lightning arrester

application:

The 10kV rear lightning arrester is installed behind the front and rear connectors of the dry ring network cabinet, inflatable cabinet, tap box and high-voltage switch cabinet. It can provide reliable overvoltage protection for electrical systems. The outer semi-conductive layer of the shielded arrester ensures the personal safety of installation and maintenance personnel and the safe operation of the equipment. The unique waterproof and moisture-proof properties ensure the safe and reliable operation of the product in harsh environments.
