Shielded and unshielded lines do not have a certain difference in vulnerability to lightning damage, they can be affected by lightning, but the specific situation depends on a variety of factors.

First of all, lightning damage is mainly due to the high voltage and high current generated by lightning transmitted through the line to the equipment, resulting in equipment damage. Therefore, whether it is a shielded line or an unshielded line, if its insulation and protective layer cannot withstand the high voltage and high current generated by lightning, damage may occur.

However, shielded lines have certain advantages in lightning protection. Because the shielded wire has a metal shielding layer, when the high voltage and high current generated by lightning pass through the line, the shielding layer can play a certain role of shunt and ground, and introduce some lightning into the ground, thereby reducing the impact on the internal wire and equipment. The non-shielded line is relatively weak in lightning protection due to the absence of this metal shielding layer.

However, it should be noted that the lightning protection ability of the shielding line is not certain, and its effect also depends on the grounding of the shielding layer, the layout of the line and the surrounding environment. If the shielding layer is poorly grounded or the line layout is unreasonable, the lightning protection effect of the shielding line may be greatly reduced.

Therefore, in areas with frequent lightning strikes or where lightning protection requirements are high, you are advised to use shielding cables with good lightning protection performance, and ensure that the shielding layer is well grounded and the cable layout is reasonable. At the same time, you can also take other lightning protection measures, such as installing lightning arrester, grounding device, etc., to further improve the lightning protection effect.
