If a lightning arrester has been installed on the power line, is it still necessary to provide lightning protection for the signal port?

Power lines and signal lines need to be protected separately. Generally, signal ports are often overlooked. Representative signal lines include network cables, RS485, RS232, analog signals, etc. These lines are all made of copper cables and are prone to surge detection, which can cause damage to equipment such as switches and PLCS. Therefore, the installation of signal lightning protectors is very necessary.

Will signal lightning arresters affect signal attenuation?

The interfaces of KILOAMP signal lightning arresters are all matched with the equipment interfaces. High-quality connectors are all selected, and the insertion losses are all less than 0.5dB. Therefore, the signal attenuation can almost be ignored.

What should be noted when selecting a signal lightning arrester?

The selection of signal lightning arresters mainly needs to consider aspects such as interface type, voltage, transmission rate, and bandwidth. The more common ones are network cables, RS485, RS232, analog signals, etc. Only when these parameters are matched can the communication of the equipment be guaranteed not to be affected. The current-carrying capacity Imax of a signal lightning arrester is generally 5-10kA, and this indicator does not need to be overly concerned about.

Does the signal lightning arrester need power supply?

Signal lightning arresters are passive and do not require power supply. Their internal protection is mainly achieved through components such as gas discharge tubes (GDT) and TVS.

How many ports can a signal lightning arrester reach at most?

Signal lightning arresters are generally single-port, but they can also be multi-port depending on the number of device interfaces, typically including 4/8/16/24 ports, etc. The installation methods also support rail mounting and rack-mounted mounting.

Signal Surge Protector

The signal lines of the equipment are copper cables, which are relatively prone to surge sensing and also require lightning protection. Representative ones include network cables, RS485, RS232, analog signals, etc., which can cause damage to equipment such as switches and PLCS.

Types of Signal Surge Protector

Features of Signal Surge Protector

01

1

Rich interfaces, select different interfaces according to different communication lines to ensure interface adaptation;
02

2

Low insertion loss and high-quality connectors are used to ensure minimal signal attenuation when SPD is connected;
03

3

Multi-level protection circuit design reduces the residual voltage value to a minimum and protects the circuits of back-end equipment to the greatest extent.
