Surge Arresters Used In Network Signal Lines

In many cabling systems, it's not uncommon for signal lines and power lines to share a single network cable when network signals (including Ethernet and PoE-powered networks) need to be laid outdoors or over long distances. Lightning surges and electromagnetic interference can be conducted through these lines. To mitigate these risks, network systems typically deploy protection 11 kv lighting arrester to handle both signals and power transmitted over Ethernet or PoE networks.

Protection 11 kv lightning arrester is designed for network data pairs and power lines. In standard Ethernet scenarios, where only data transmission occurs, protection 11kv 10ka lightning arrester on data lines provides surge protection for signal lines. For PoE network environments—where the network cable not only carries data but also powers devices—protection 11kv lighting arrester extends to both data lines and DC power lines. This allows protection for everything from standard router and switch connections to PoE-powered cameras and wireless access points.
