Background

The natural phenomena of lightning can release huge energy which can reach hundreds of thousands of amperes of current and thousands of volts of voltage. Even if the lightning action time is only 100 mu s each time, the destructive effect caused by the lightning is enough to cause disasters. The risk of the communication cable under the action of lightning firing is particularly significant. In order to improve the lightning protection performance of communication cables, technologists try to reduce the resistance of the metal cable sheath of the cable and increase the dielectric strength between the cable sheath and the core wire. For example, the cable sheath is made of aluminum sheath, and the core wire protective layer is made of lead sheath; when the skin and lead are the same thickness, the resistance of the skin is only 1/7 times the resistance of the lead. Such an aluminum-clad cable would have a higher lightning protection capability. However, the use of aluminum skin is not sufficient, and a plastic protective layer is usually arranged outside the aluminum skin. And the plastic protective layer is easy to be punctured during lightning stroke to form a pinhole. The metal sheath of the cable can be corroded by rain and moisture. To prevent this, the technician then "dresses" the cable with a semiconducting outer sheath over the cable metal sheath. Thus, the outer protective layer is conductive in lightning strike, so that lightning current can be smoothly led into the ground, and the cable has the performance of corrosion resistance due to the semiconductor outer protective layer.

But the prior art often is not convenient for accomodate unnecessary cable and protect when the installation lightning-arrest cable to it is pleasing to the eye when using, makes it receive the damage easily simultaneously, and then causes the lightning protection effect lower, thereby brings some potential safety hazards.
