Lightning Protection for Coaxial Lines

Contrary to what is commonly known, lightning strikes cause damage to systems at a rate of 70% through data, communication, and coaxial lines. Due to cable lengths, strikes coming from these lines can be carried for kilometers. For example, consider a GSM tower; even if you protect all power lines with LV surge arrester systems at the highest protection level, the strike may come through the coaxial line and damage the system. Therefore, the Protection of Coaxial Lines Against Lightning is extremely important. Generally, this problem is encountered more frequently with damages caused by strikes coming from camera and satellite lines. While the risk is very high in a highly critical data center; in an apartment flat, a strike coming from the satellite line can damage the entire television system. In order not to experience these problems, coaxial line protections, which are included in the Type 3 surge arrester category, integrated in series into the system, and whose technologies are highly important, should be used in every system.

Coaxial line protections should be located at both ends of the line. As a common feature of series-connected Type 3 class surge arresters, they protect the line to which they are closest. For example, in a camera system, while protection is required at the DVR device input, protection must also be applied at the camera system input.

The most critical point in LV surge arrester selection for coaxial lines is the frequency value of the system. A product suitable for the system frequency value should be selected. Additionally, the system Uc continuous voltage level is extremely important for trouble-free operation. As stated, the products are integrated into the system in series; the upper parts of the series-integrated products must definitely be connected to the grounding line. Gas discharge tubes are predominantly present inside the products and they are activated in 25 ns.

In coaxial surge arresters, the product connector structure is also important. When we look at the most commonly used products, F connector; UHF connector; N connector; BNC connector; SMA connector stand out.
