Lightning protection cables are available in a range of components and measurements to fulfill the full selection of lightning security conditions.
It is usually achievable to possess varying resistance values for grounding electrodes even on the identical construction.
chapeau paratonnerre. The so-termed rods, the paper explained, “consisted of a woven steel ribbon which encircled the hat and terminated in a lengthy silver twine trailing on the bottom.”
