Lightning rod cable. A copper cable is employed to connect the lightning rod to the grounding substance. It ought to be of ample dimension to manage the electrical present produced for the duration of a lightning strike.
Ever heard about lightning rods? Or maybe you realize them as lightning conductors. Either way, these equipment have been around For the reason that 18th century. Owing to Benjamin Franklin, their purpose has usually been straightforward – give lightning an uncomplicated path to the ground and retain properties Protected.
How could the lightning rod terrify and offend persons? It is just a piece of metal linked by a wire to the bottom!

Building a technique of air terminals projecting only ten inches higher than these structural points of emphasis and alongside ridges and edges has been demonstrated, in a lot more than a century of apply, to provide interception of some ninety five% of recorded lightning flashes, including the most violent. Some decrease likely lightning strokes could theoretically connect on flat planes from strike terminations made to the Benchmarks, but the results are within suitable boundaries for standard design. Taking into consideration the reduced Electrical power degree needed for your bypass, the other structural grounding parts A part of a whole lightning security method, plus the random chance for connection with a system element in any case, this technique of constructing security is considered most successful.
Lightning Security Systems France® provides you with an in depth catalog of lightning rods, surge arresters and earthings based upon benchmarks evolutions, technological advances along with the demands expressed by our prospects.
” In South Carolina a physician managed to recreate Franklin’s kite experiment but was restrained from setting up a lightning rod by his anxious neighbors. Why were they terrified of a rod of metallic?
