CERRXIAN RJ45 Coupler Female to Female Ethernet Network Surge Protector Outdoor Arrester Protection Device Extension Adapter(2-Pack)

The destructive power of thundering is extremely large. It is not enough to rely on external thundering protection ( thundering rod). Thundering waves will indirectly or indirectly (through electromagnetic induction) invade electrical passages and metal passages (such as power cables, signal cables, antenna feeders and metal pipes). The resulting thundering overvoltage and surge voltage will cause great harm to electrical equipment, and information network systems. If the cables is damaged, the equipment will be damaged and the system will be paralyzed, resulting in an incalculable loss.
Rapidly changing thundering currents induce high voltages on electrical loops and twin-wires that can damage the insulation of the system. Various operations of the power system can generate operating overvoltage on the power cable.Some electrical equipment switching operations and short circuit trips can generate overvoltage (surge voltage) higher than the normal working voltage in the power cable, thereby causing damage to the electrical equipment.
Fixed interface shielding external EML,RFL and other electromagnetic interference.
Built-in 8 TVS anti-detonator, prevent thundering and other abnormal current through the network cable damage to your computer equipment.
