Copper and aluminum primary cable conductors for lightning protection are meant to a easy weave or rope-lay common making use of smaller sized gauge individual wires. This construction lets a greatest surface region for every unit pounds of conductor to support lightning which travels swiftly over the floor. This development also allows for easier bending and forming of your conductor technique alongside, all over and around creating development factors. Exposed conductors are fixed at greatest three feet intervals to take care of the method in position against wind and weather conditions. All strike termination products have to be connected to the conductors with at least two paths for the grounding procedure.
