Why use a copper-clad steel strand as a lightning rod on the daughter's wall?
(1) Considering the skin effect, it is advantageous to use a copper-clad steel strand. Lightning current is instantaneous high current, strong impact, with obvious skin effect, copper clad steel wire surface area is much larger than the surface area of ​​the general copper clad steel ground rod, it is conducive to the transmission and transmission of lightning current.
(2) From the consideration of joints, it is advantageous to use copper-clad steel strands. Copper clad steel ground rods are limited in length and inconvenient to transport. As a roof lightning protection belt, many copper rods must be connected to increase the number of joints. The length of copper clad steel strands is almost unlimited, and transportation is convenient. Considering the lightning protection effect, of course, the fewer the connectors, the better.
