Surge Arresters Need To Provide Comprehensive Protection For Power Supply, Signal, And Control Lines.

As a core protection device in electrical systems, the design concept of 11 kv lighting arrester is not limited to overvoltage handling of a single path, but extends to comprehensive protection of multiple channels such as power supply, signal and control lines.

Power lines carry the primary energy supply, signal lines transmit control commands and feedback information, and control lines are responsible for the response and actions of automated execution units. These three types of lines play different but equally important roles in system operation. If a local circuit is struck by lightning or a surge and not managed in time, overvoltage can propagate to internal equipment through different paths, affecting equipment performance and even causing unit failure.
