Further, the lightning protection assembly also includes an absorber 2 and a peak clipper 3, which are both arranged on the lightning rod 1, and the absorber 2 is arranged at the upper end of the peak clipper 3. As the thundercloud approaches the lightning rod 1, it is introduced into the lightning wave absorber 2 by the lightning rod 1, and the absorber 2 converts the lightning energy into heat energy for dissipation, and then transmits it to the lightning wave peak clipping device (i.e., the peak clipper 3) to reduce and absorb the lightning wave peak. It has been proved by experiments that after the lightning peak current is processed, the peak is reduced by 56.6% (the impact current is 94.0kA when no-load, and after the absorber 2 and the peak clipper 3 are connected, the peak of the impact current is reduced and absorbed to 40.8kA). The lightning protection level of cement pole towers and lines is greatly improved, and the direct strike, counterattack, and bypass strike of lightning are effectively prevented from affecting the power supply.

In actual application, the spacing between the first bracket clamp 7 and the second bracket clamp 9 can be adjusted according to actual conditions to facilitate the installation of the mounting bracket 6.

[0027] In this embodiment, the first bracket clamp 7 and the second bracket clamp 9 are both provided with support tubes, and the support tubes are provided with support screws and gaskets. The fixing of the mounting bracket 6 is achieved by adjusting the support screws. It can be imagined that the provision of gaskets can facilitate the installation and fixing of the mounting bracket 6.

[0028] In this embodiment, the mounting assembly further includes a counter clamp 12, which fixes the counter 10 through the counter bracket, and the second bracket clamp 9 is connected to the counter clamp 12 through the protection line 11. The first bracket clamp 7, the second bracket clamp 9 and the counter clamp 12 all use round-angle clamps to fix the tubular connector to the bracket, and the bracket can be adjusted in multiple directions and angles, which improves the installation reliability and greatly facilitates the installation.

[0029] It is conceivable that in some embodiments, a protective device may be further provided, such as providing a protective pin (not shown) on the mounting bracket 6, so that when a fault occurs in the grounding down lead 5, lightning energy can be discharged.
