Surge Arresters In Poe Power Supply Environments Cannot Be Ignored.

For PoE equipment deployed outdoors or in exposed environments, surges from surrounding lightning or power system switching can travel along the cables into the equipment, causing damage. While lightning protection is already a consideration in many network equipment designs, line-level protection remains crucial. This is one of the key reasons why 9kv lightning arrester was included in the planning during the system design phase. Proper selection of the lighting arrester 11kv data cable for the PoE power supply link is essential to mitigate the impact of external electromagnetic interference on the power supply line.
